Osteocalcin/matrix Gla protein family
PTM: Gamma-carboxyglutamate residues are formed by vitamin K dependent carboxylation by GGCX. These residues are essential for the binding of calcium (By similarity) (PubMed:1068450, PubMed:12820886). Decarboxylation promotes the hormone activity (By similarity). {ECO:0000250|UniProtKB:P86546, ECO:0000255|PROSITE-ProRule:PRU00463, ECO:0000269|PubMed:1068450, ECO:0000269|PubMed:12820886}.

FUNCTION: The carboxylated form is one of the main organic components of the bone matrix, which constitutes 1-2% of the total bone protein (PubMed:1068450). It acts as a negative regulator of bone formation and is required to limit bone formation without impairing bone resorption or mineralization. The carboxylated form binds strongly to apatite and calcium (By similarity). {ECO:0000250|UniProtKB:P86546, ECO:0000269|PubMed:1068450}.; FUNCTION: The uncarboxylated form acts as a hormone secreted by osteoblasts, which regulates different cellular processes, such as energy metabolism, male fertility and brain development. Regulates of energy metabolism by acting as a hormone favoring pancreatic beta-cell proliferation, insulin secretion and sensitivity and energy expenditure. Uncarboxylated osteocalcin hormone also promotes testosterone production in the testes: acts as a ligand for G protein-coupled receptor GPRC6A at the surface of Leydig cells, initiating a signaling response that promotes the expression of enzymes required for testosterone synthesis in a CREB-dependent manner. Also acts as a regulator of brain development: osteocalcin hormone crosses the blood-brain barrier and acts as a ligand for GPR158 on neurons, initiating a signaling response that prevents neuronal apoptosis in the hippocampus, favors the synthesis of all monoamine neurotransmitters and inhibits that of gamma-aminobutyric acid (GABA). Osteocalcin also crosses the placenta during pregnancy and maternal osteocalcin is required for fetal brain development. {ECO:0000250|UniProtKB:P86546}.

FUNCTION: Molecular chaperone that promotes the maturation, structural maintenance and proper regulation of specific target proteins involved for instance in cell cycle control and signal transduction. Undergoes a functional cycle that is linked to its ATPase activity. This cycle probably induces conformational changes in the client proteins, thereby causing their activation. Interacts dynamically with various co-chaperones that modulate its substrate recognition, ATPase cycle and chaperone function. Together with Hop and piwi, mediates canalization, also known as developmental robustness, likely via epigenetic silencing of existing genetic variants and suppression of transposon-induced new genetic variation. Required for piRNA biogenesis by facilitating loading of piRNAs into PIWI proteins. {ECO:0000269|PubMed:21186352, ECO:0000269|PubMed:22902557}.

FUNCTION: Molecular chaperone that promotes the maturation, structural maintenance and proper regulation of specific target proteins involved in cell cycle control and signal transduction. Undergoes a functional cycle that is linked to its ATPase activity. The nucleotide-free form of the dimer is found in an open conformation in which the N-termini are not dimerized and the complex is ready for client protein binding. Binding of ATP induces large conformational changes, resulting in the formation of a ring-like closed structure in which the N-terminal domains associate intramolecularly with the middle domain and also dimerize with each other, stimulating their intrinsic ATPase activity and acting as a clamp on the substrate. Finally, ATP hydrolysis results in the release of the substrate. This cycle probably induces conformational changes in the client proteins, thereby causing their activation. Interacts dynamically with various co-chaperones that modulate its substrate recognition, ATPase cycle and chaperone function. Required for growth at high temperatures. {ECO:0000269|PubMed:17114002}.

Leguminous lectin family
PTM: The mature chain consists of residues 164-281 followed by 30-148. To form a mature chain the precursor undergoes further post-translational modification after removal of the signal sequence; cleavage after Asn at positions 148, 163, and 281 is followed by transposition and ligation (By formation of a new peptide bond) of residues 164-281 and 30-148 (PubMed:34235541). This maturation (circular permutation) relies on the legumain AEP1 activity and leads to an increased stability of conA after heat stress and at various pH (PubMed:34235541). {ECO:0000269|PubMed:34235541}.

FUNCTION: Ricin is highly toxic to animal cells, and to a lesser extent to plant cells.; FUNCTION: [Ricin A chain]: Acts as a glycosidase that removes a specific adenine residue from an exposed loop of the 28S rRNA (A4324 in mammals), leading to rRNA breakage. As this loop is involved in elongation factor binding, modified ribosomes are catalytically inactive and unable to support protein synthesis. Can inactivate a few thousand ribosomes per minute, faster than the cell can make new ones. Therefore a single molecule can kill an animal cell.; FUNCTION: [Ricin B chain]: Binds to beta-D-galactopyranoside moieties on cell surface glycoproteins and glycolipids and facilitates the entry into the cell of the A chain. Also responsible for cell agglutination (Lectin activity).

PTM: During host cell invasion, proteolytically cleaved at the cell membrane in the region I by a papain-like cysteine protease of parasite origin (PubMed:15630135, PubMed:29554083). Cleavage is triggered by the sporozoite contact with highly sulfated heparan sulfate proteoglycans (HSPGs) present on the host hepatocyte cell surface (By similarity). Cleavage exposes the TSP type-1 (TSR) domain and is required for productive invasion of host hepatocytes but not for adhesion to the host cell membrane (PubMed:15630135). Cleavage is dispensable for sporozoite development in the oocyst, motility and for traversal of host and vector cells (By similarity). {ECO:0000250|UniProtKB:P23093, ECO:0000269|PubMed:15630135, ECO:0000269|PubMed:29554083}.; PTM: O-glycosylated; maybe by POFUT2. {ECO:0000250|UniProtKB:P19597}.

FUNCTION: Mediates the transport of melibiose and other galactosides by a symport mechanism (PubMed:2185831, PubMed:3311166, PubMed:3316227, PubMed:45782, PubMed:7703254). Can use sodium, lithium and protons as coupling cations, depending on the sugar substrate and the cationic environment (PubMed:3311166, PubMed:3316227, PubMed:45782, PubMed:7703254). Alpha-galactosides (melibiose, raffinose, p-nitrophenyl-alpha-galactoside or methyl-alpha-galactoside) are cotransported with either Na(+) or H(+), whereas beta-galactosides (lactose, L-arabinose-beta-D-galactoside, D-fructose-beta-D-galactoside, methyl-beta-galactoside or p-nitrophenyl-beta-galactoside) are cotransported with Na(+) or Li(+) but not H(+) (PubMed:3311166, PubMed:45782). The monosaccharide D-galactose can use either Na(+) or H(+) for cotransport whereas D-fucose, L-arabinose and D-galactosamine can use only Na(+) (PubMed:3311166). {ECO:0000269|PubMed:2185831, ECO:0000269|PubMed:3311166, ECO:0000269|PubMed:3316227, ECO:0000269|PubMed:45782, ECO:0000269|PubMed:7703254}.

FUNCTION: Interacts with outer membrane receptor proteins that carry out high-affinity binding and energy dependent uptake into the periplasmic space of specific substrates such as cobalamin, and various iron compounds (such as iron dicitrate, enterochelin, aerobactin, etc.). In the absence of TonB these receptors bind their substrates but do not carry out active transport. TonB also interacts with some colicins and is involved in the energy-dependent, irreversible steps of bacteriophages phi 80 and T1 infection. It could act to transduce energy from the cytoplasmic membrane to specific energy-requiring processes in the outer membrane, resulting in the release into the periplasm of ligands bound by these outer membrane proteins. Implicated in hydroxy radical-mediated cell death induced by hydroxyurea treatment (PubMed:20005847). {ECO:0000269|PubMed:20005847}.

FUNCTION: Receptor for the attractant L-serine and related amino acids. Is also responsible for chemotaxis away from a wide range of repellents, including leucine, indole, and weak acids.; FUNCTION: Chemotactic-signal transducers respond to changes in the concentration of attractants and repellents in the environment, transduce a signal from the outside to the inside of the cell, and facilitate sensory adaptation through the variation of the level of methylation. Attractants increase the level of methylation while repellents decrease the level of methylation, the methyl groups are added by the methyltransferase CheR and removed by the methylesterase CheB.

FUNCTION: Plays a role in the inhibition of the host innate and adaptive immune responses. Possesses five immunoglobulin-binding domains that capture both the fragment crystallizable region (Fc region) and the Fab region (part of Ig that identifies antigen) of immunoglobulins (PubMed:10805799, PubMed:2938951, PubMed:4163007). In turn, Staphylococcus aureus is protected from phagocytic killing via inhibition of Ig Fc region. In addition, the host elicited B-cell response is prevented due to a decrease of antibody-secreting cell proliferation that enter the bone marrow, thereby decreasing long-term antibody production. Inhibits osteogenesis by preventing osteoblast proliferation and expression of alkaline phosphatase, type I collagen, osteopontin and osteocalcin. Acts directly as a pro-inflammatory factor in the lung through its ability to bind and activate tumor necrosis factor alpha receptor 1/TNFRSF1A (By similarity). {ECO:0000250|UniProtKB:A0A0H3K686, ECO:0000269|PubMed:10805799, ECO:0000269|PubMed:2938951, ECO:0000269|PubMed:4163007}.

FUNCTION: Involved in ribosomal large subunit biogenesis (By similarity). Acts both as a positive transcription factor for 5S RNA genes, and as a specific RNA binding protein that complexes with 5S RNA in oocytes to form the 7S ribonucleoprotein storage particle. May play an essential role in the developmental change in 5S RNA gene expression. Interacts with the internal control region (ICR) of approximately 50 bases within the 5S RNA genes, is required for correct transcription of these genes by RNA polymerase III (PubMed:1538401, PubMed:1762917, PubMed:2253880).

FUNCTION: Plays a key role in the initiation and regulation of chromosomal replication. Binds in an ATP-dependent fashion to the origin of replication (oriC) to initiate formation of the DNA replication initiation complex exactly once per cell cycle. Binds the DnaA box (consensus sequence 5'-TTATC[CA]A[CA]A-3'); subsequent binding of DNA polymerase III subunits leads to replisome formation. The DnaA-ATP form converts to DnaA-ADP; once converted to ADP the protein cannot initiate replication, ensuring only 1 round of replication per cell cycle. DnaA can inhibit its own gene expression as well as that of other genes such as dam, rpoH, ftsA and mioC.; FUNCTION: Also required for replication of plasmid DNA; binds 4 dnaA boxes in the minimal plasmid RK2 replication origin (oriV).

FUNCTION: Performs inversion of a viral 3 kp segment (G-segment) that encodes two alternate pairs of tail fiber proteins thereby modifying the host specificity of the virus. Binds as a dimer to the viral gix sites which are 34-bp palindromic sequences that flank the invertible G-segment. Catalyzes site-specific recombination in the presence of the host factor Fis. Gin dimers bound to each of the gix sites and host factor Fis bound to the enhancer come together to form the synaptic complex. Each Gin monomer introduces a nick and becomes covalently attached to the 5'-phosphate of the DNA, resulting in double-stranded staggered breaks at both recombination sites. A 180 degrees rotation of one of the two Gin dimers followed by religation of the DNA leads to the inversion of the G-segment (G+ or G- orientation). {ECO:0000269|PubMed:23275567, ECO:0000269|PubMed:2974801, ECO:0000269|PubMed:3159478, ECO:0000269|PubMed:6232613}.

FUNCTION: Master transcriptional regulator that mediates the response to amino acid starvation (PubMed:11390663, PubMed:29628310). Binds variations of the DNA sequence 5'-ATGA[CG]TCAT-3' in canonical nucleosome-depleted 5'-positioned promoters, and also within coding sequences and 3' non-coding regions (PubMed:11390663, PubMed:1473154, PubMed:1939099, PubMed:2204805, PubMed:2277632, PubMed:29628310, PubMed:3530496, PubMed:3532321, PubMed:3678204, PubMed:7664107). During nutrient starvation (low or poor amino acid, carbon or purine sources), it activates genes required for amino acid biosynthesis and transport, autophagy, cofactor biosynthesis and transport, mitochondrial transport, and additional downstream transcription factors (PubMed:10733573, PubMed:11390663, PubMed:1939099, PubMed:29628310, PubMed:7862116, PubMed:8336737). Activates transcription by recruiting multiple coactivators, including the mediator complex, the SAGA complex, and the SWI/SNF complex, to enable assembly of the pre-initiation complex at core promoters (PubMed:10549298, PubMed:19940160, PubMed:9488488). {ECO:0000269|PubMed:10549298, ECO:0000269|PubMed:10733573, ECO:0000269|PubMed:11390663, ECO:0000269|PubMed:1473154, ECO:0000269|PubMed:1939099, ECO:0000269|PubMed:19940160, ECO:0000269|PubMed:2204805, ECO:0000269|PubMed:2277632, ECO:0000269|PubMed:29628310, ECO:0000269|PubMed:3530496, ECO:0000269|PubMed:3532321, ECO:0000269|PubMed:3678204, ECO:0000269|PubMed:7664107, ECO:0000269|PubMed:7862116, ECO:0000269|PubMed:8336737, ECO:0000269|PubMed:9488488}.

FUNCTION: Isoform large T antigen is a key early protein essential for both driving viral replication and inducing cellular transformation. Plays a role in viral genome replication by driving entry of quiescent cells into the cell cycle and by autoregulating the synthesis of viral early mRNA. Displays highly oncogenic activities by corrupting the host cellular checkpoint mechanisms that guard cell division and the transcription, replication, and repair of DNA. Participates in the modulation of cellular gene expression preceeding viral DNA replication. This step involves binding to host key cell cycle regulators retinoblastoma protein RB1/pRb and TP53. Induces the disassembly of host E2F1 transcription factors from RB1, thus promoting transcriptional activation of E2F1-regulated S-phase genes. Inhibits host TP53 binding to DNA, abrogating the ability of TP53 to stimulate gene expression. Plays the role of a TFIID-associated factor (TAF) in transcription initiation for all three RNA polymerases, by stabilizing the TBP-TFIIA complex on promoters. Initiates viral DNA replication and unwinding via interactions with the viral origin of replication. Binds two adjacent sites in the SV40 origin. The replication fork movement is facilitated by Large T antigen helicase activity. Activates the transcription of viral late mRNA, through host TBP and TFIIA stabilization. Interferes with histone deacetylation mediated by HDAC1, leading to activation of transcription. May inactivate the growth-suppressing properties of the E3 ubiquitin ligase CUL7. {ECO:0000269|PubMed:15611062, ECO:0000269|PubMed:17341466, ECO:0000269|PubMed:18922873, ECO:0000269|PubMed:8647434, ECO:0000269|PubMed:9632777}.; FUNCTION: Isoform 17kT antigen targets host RBL2 for degradation and promotes cell proliferation.

FUNCTION: Forms an icosahedral capsid with a T=7 symmetry and a 40 nm diameter. The capsid is composed of 72 pentamers linked to each other by disulfide bonds and associated with VP2 or VP3 proteins. Binds to N-glycolylneuraminic analog of the ganglioside GM1 on the cell surface to provide virion attachment to target cell (PubMed:18353982). Once attached, the virion is internalized by caveolin-mediated endocytosis and traffics to the endoplasmic reticulum. Inside the endoplasmic reticulum, the protein folding machinery isomerizes VP1 interpentamer disulfide bonds, thereby triggering initial uncoating (PubMed:17981119). Next, the virion uses the endoplasmic reticulum-associated degradation machinery to probably translocate in the cytosol before reaching the nucleus (PubMed:17981119). Nuclear entry of the viral DNA involves the selective exposure and importin recognition of VP2/Vp3 nuclear localization signal. The assembly takes place in the cell nucleus. Encapsulates the genomic DNA and participates in rearranging nucleosomes around the viral DNA. The viral progenies exit the cells by lytic release. {ECO:0000269|PubMed:17981119, ECO:0000269|PubMed:18353982, ECO:0000305|PubMed:19157478}.

FUNCTION: Forms an icosahedral capsid with a T=7 symmetry and a 40 nm diameter. The capsid is composed of 72 pentamers linked to each other by disulfide bonds and associated with VP2 or VP3 proteins. Interacts with a N-linked glycoprotein containing terminal alpha(2-6)-linked sialic acids on the cell surface to provide virion attachment to target cell. The serotonergic receptor 5HT2AR also acts as a cellular receptor for JCV on human glial cells. Once attached, the virions enter predominantly by a ligand-inducible clathrin-dependent pathway and traffic to the ER. Inside the endoplasmic reticulum, the protein folding machinery isomerizes VP1 interpentamer disulfide bonds, thereby triggering initial uncoating. Next, the virion uses the endoplasmic reticulum-associated degradation machinery to probably translocate in the cytosol before reaching the nucleus. Nuclear entry of the viral DNA involves the selective exposure and importin recognition of VP2/Vp3 nuclear localization signal. In late phase of infection, neo-synthesized VP1 encapsulates replicated genomic DNA at nuclear domains called promyelocytic leukemia (PML) bodies, and participates in rearranging nucleosomes around the viral DNA. {ECO:0000269|PubMed:10666259, ECO:0000269|PubMed:9573227, ECO:0000305|PubMed:19157478}.

FUNCTION: [Isoform VP2]: Structural protein that resides within the core of the capsid surrounded by 72 VP1 pentamers. Following virus endocytosis and trafficking to the endoplasmic reticulum, VP2 and VP3 form oligomers and integrate into the endoplasmic reticulum membrane. Heterooligomer VP2-VP3 may create a viroporin for transporting the viral genome across the endoplasmic reticulum membrane to the cytoplasm. Nuclear entry of the viral DNA involves the selective exposure and importin recognition of VP2 or VP3 nuclear localization signal (shared C-terminus). Plays a role in virion assembly within the nucleus in particular through a DNA-binding domain located in the C-terminal region. A N-terminal myristoylation suggests a scaffold function for virion assembly. The viral progenies exit the cells by lytic release. Isoform VP2 may repress SP1 activation of the SV40 early promoter, via specific protein-protein and protein-DNA interactions. {ECO:0000269|PubMed:17189196, ECO:0000269|PubMed:3031509, ECO:0000269|PubMed:7815491}.; FUNCTION: [Isoform VP3]: Structural protein that resides within the core of the capsid surrounded by 72 VP1 pentamers.

FUNCTION: Minor protein of the capsid that localizes along the inner surface of the virion, within the central cavities beneath the L1 pentamers. Plays a role in capsid stabilization through interaction with the major capsid protein L1. Once the virion enters the host cell, L2 escorts the genomic DNA into the nucleus by promoting escape from the endosomal compartments and traffic through the host Golgi network. Mechanistically, the C-terminus of L2 possesses a cell-penetrating peptide that protudes from the host endosome, interacts with host cytoplasmic retromer cargo and thereby mediates the capsid delivery to the host trans-Golgi network. Plays a role through its interaction with host dynein in the intracellular microtubule-dependent transport of viral capsid toward the nucleus. Mediates the viral genome import into the nucleus through binding to host importins. Once within the nucleus, L2 localizes viral genomes to host PML bodies in order to activate early gene expression for establishment of infection. Later on, promotes late gene expression by interacting with the viral E2 protein and by inhibiting its transcriptional activation functions. During virion assembly, encapsidates the genome by direct interaction with the viral DNA. {ECO:0000255|HAMAP-Rule:MF_04003, ECO:0000269|PubMed:15507604, ECO:0000269|PubMed:15681049, ECO:0000269|PubMed:21166973, ECO:0000269|PubMed:25693203, ECO:0000269|PubMed:30122350, ECO:0000269|PubMed:8553535}.

FUNCTION: ATP-dependent DNA helicase required for initiation of viral DNA replication. It forms a complex with the viral E2 protein. The E1-E2 complex binds to the replication origin which contains binding sites for both proteins. During the initial step, a dimer of E1 interacts with a dimer of protein E2 leading to a complex that binds the viral origin of replication with high specificity. Then, a second dimer of E1 displaces the E2 dimer in an ATP-dependent manner to form the E1 tetramer. Following this, two E1 monomers are added to each half of the site, which results in the formation of two E1 trimers on the viral ori. Subsequently, two hexamers will be created. The double hexamer acts as a bi-directional helicase machinery and unwinds the viral DNA and then recruits the host DNA polymerase to start replication. {ECO:0000255|HAMAP-Rule:MF_04000, ECO:0000269|PubMed:11005821, ECO:0000269|PubMed:14747526, ECO:0000269|PubMed:16415033, ECO:0000269|PubMed:1846806}.

FUNCTION: Plays a role in the initiation of viral DNA replication. A dimer of E2 interacts with a dimer of E1 in order to improve specificity of E1 DNA binding activity. Once the complex recognizes and binds DNA at specific sites, the E2 dimer is removed from DNA. E2 also regulates viral transcription through binding to the E2RE response element (5'-ACCNNNNNNGGT-3') present in multiple copies in the regulatory regions of the viral genome. Activates or represses transcription depending on E2RE's position with regards to proximal promoter elements including the TATA-box. Repression occurs by sterically hindering the assembly of the transcription initiation complex. {ECO:0000255|HAMAP-Rule:MF_04001, ECO:0000269|PubMed:1326651, ECO:0000269|PubMed:15681049, ECO:0000269|PubMed:16611886, ECO:0000269|PubMed:25340539, ECO:0000269|PubMed:26365679, ECO:0000269|PubMed:3033289}.

FUNCTION: Plays a role in the initiation of viral DNA replication. A dimer of E2 interacts with a dimer of E1 in order to improve specificity of E1 DNA binding activity. Once the complex recognizes and binds DNA at specific sites, the E2 dimer is removed from DNA. E2 also regulates viral transcription through binding to the E2RE response element (5'-ACCNNNNNNGGT-3') present in multiple copies in the regulatory regions of the viral genome. Activates or represses transcription depending on E2RE's position with regards to proximal promoter elements including the TATA-box. Repression occurs by sterically hindering the assembly of the transcription initiation complex. {ECO:0000255|HAMAP-Rule:MF_04001}.

FUNCTION: Plays a major role in the induction and maintenance of cellular transformation. Acts mainly as an oncoprotein by stimulating the destruction of many host cell key regulatory proteins. E6 associates with host UBE3A/E6-AP ubiquitin-protein ligase, and inactivates tumor suppressors TP53 and TP73 by targeting them to the 26S proteasome for degradation. In turn, DNA damage and chromosomal instabilities increase and lead to cell proliferation and cancer development. The complex E6/E6AP targets several other substrates to degradation via the proteasome including host DLG1 or NFX1, a repressor of human telomerase reverse transcriptase (hTERT). The resulting increased expression of hTERT prevents the shortening of telomere length leading to cell immortalization. Other cellular targets including BAK1, Fas-associated death domain-containing protein (FADD) and procaspase 8, are degraded by E6/E6AP causing inhibition of apoptosis. E6 also inhibits immune response by interacting with host IRF3 and TYK2. These interactions prevent IRF3 transcriptional activities and inhibit TYK2-mediated JAK-STAT activation by interferon alpha resulting in inhibition of the interferon signaling pathway. {ECO:0000255|HAMAP-Rule:MF_04006, ECO:0000269|PubMed:10523825, ECO:0000269|PubMed:10523853, ECO:0000269|PubMed:8598912, ECO:0000269|PubMed:9326658, ECO:0000269|PubMed:9649509}.

FUNCTION: Plays a role in viral genome replication by driving entry of quiescent cells into the cell cycle. Stimulation of progression from G1 to S phase allows the virus to efficiently use the cellular DNA replicating machinery to achieve viral genome replication. E7 protein has both transforming and trans-activating activities. Induces the disassembly of the E2F1 transcription factor from RB1, with subsequent transcriptional activation of E2F1-regulated S-phase genes. Interferes with host histone deacetylation mediated by HDAC1 and HDAC2, leading to transcription activation. Also plays a role in the inhibition of both antiviral and antiproliferative functions of host interferon alpha. Interaction with host TMEM173/STING impairs the ability of TMEM173/STING to sense cytosolic DNA and promote the production of type I interferon (IFN-alpha and IFN-beta). {ECO:0000255|HAMAP-Rule:MF_04004, ECO:0000269|PubMed:11080488, ECO:0000269|PubMed:1316611, ECO:0000269|PubMed:2836062}.

FUNCTION: Multifunctional protein which displays endonuclease and helicase activities required for initiating and directing viral DNA replication (PubMed:12050365). Also plays a role in viral packaging and transactivation of several promoters (PubMed:7636987). Binds site-specifically to 2-3 approximate tandem copies of the tetranucleotide 5'TGGT3' within the origins of replication (Ori), unwinds this hairpin region and nicks one DNA strand thereby initiating the rolling circle replication (RCR) (PubMed:12050365, PubMed:17898054, PubMed:9349487). Cooperatively binds Ori with host PIF and probably other host factors, which activate the nickase function of NS1 (PubMed:11435581, PubMed:12050365). Becomes covalently attached to the 5' end of the nick and provides a 3'OH for priming DNA synthesis (PubMed:12050365). The helicase activity unwinds DNA in a 3'-5' direction on the longer strand (PubMed:12050365). Participates in the transcriptional regulation of several promoters including the viral p38 promoter that regulates the expression of VP1 and VP2 transcripts (PubMed:7636987, PubMed:8551622). Inhibits the host cell cycle during the G1/S transition, the S-phase, and the G2/M transition (PubMed:11602746, PubMed:9188601). These arrests may provide essential cellular factors for viral DNA replication. Promotes apoptosis in host cell (PubMed:21295324). {ECO:0000269|PubMed:11435581, ECO:0000269|PubMed:11602746, ECO:0000269|PubMed:12050365, ECO:0000269|PubMed:17898054, ECO:0000269|PubMed:21295324, ECO:0000269|PubMed:7636987, ECO:0000269|PubMed:8551622, ECO:0000269|PubMed:9188601, ECO:0000269|PubMed:9349487}.

FUNCTION: The large envelope protein exists in two topological conformations, one which is termed 'external' or Le-HBsAg and the other 'internal' or Li-HBsAg. In its external conformation the protein attaches the virus to cell receptors and thereby initiating infection. This interaction determines the species specificity and liver tropism. This attachment induces virion internalization predominantly through caveolin-mediated endocytosis. The large envelope protein also assures fusion between virion membrane and endosomal membrane. In its internal conformation the protein plays a role in virion morphogenesis and mediates the contact with the nucleocapsid like a matrix protein. {ECO:0000255|HAMAP-Rule:MF_04075}.; FUNCTION: The middle envelope protein plays an important role in the budding of the virion. It is involved in the induction of budding in a nucleocapsid independent way. In this process the majority of envelope proteins bud to form subviral lipoprotein particles of 22 nm of diameter that do not contain a nucleocapsid. {ECO:0000255|HAMAP-Rule:MF_04075}.

FUNCTION: The large envelope protein exists in two topological conformations, one which is termed 'external' or Le-HBsAg and the other 'internal' or Li-HBsAg. In its external conformation the protein attaches the virus to cell receptors and thereby initiating infection. This interaction determines the species specificity and liver tropism. This attachment induces virion internalization predominantly through caveolin-mediated endocytosis. The large envelope protein also assures fusion between virion membrane and endosomal membrane. In its internal conformation the protein plays a role in virion morphogenesis and mediates the contact with the nucleocapsid like a matrix protein. {ECO:0000255|HAMAP-Rule:MF_04075}.; FUNCTION: The middle envelope protein plays an important role in the budding of the virion. It is involved in the induction of budding in a nucleocapsid independent way. In this process the majority of envelope proteins bud to form subviral lipoprotein particles of 22 nm of diameter that do not contain a nucleocapsid. {ECO:0000255|HAMAP-Rule:MF_04075}.

FUNCTION: Self assembles to form an icosahedral capsid. Most capsids appear to be large particles with an icosahedral symmetry of T=4 and consist of 240 copies of capsid protein, though a fraction forms smaller T=3 particles consisting of 180 capsid proteins. Entering capsids are transported along microtubules to the nucleus. Phosphorylation of the capsid is thought to induce exposure of nuclear localization signal in the C-terminal portion of the capsid protein that allows binding to the nuclear pore complex via the importin (karyopherin-) alpha and beta. Capsids are imported in intact form through the nuclear pore into the nuclear basket, where it probably binds NUP153. Only capsids that contain the mature viral genome can release the viral DNA and capsid protein into the nucleoplasm. Immature capsids get stuck in the basket. Capsids encapsulate the pre-genomic RNA and the P protein. Pre-genomic RNA is reverse-transcribed into DNA while the capsid is still in the cytoplasm. The capsid can then either be directed to the nucleus, providing more genomes for transcription, or bud through the endoplasmic reticulum to provide new virions. {ECO:0000255|HAMAP-Rule:MF_04076}.

FUNCTION: Multifunctional enzyme that converts the viral RNA genome into dsDNA in viral cytoplasmic capsids. This enzyme displays a DNA polymerase activity that can copy either DNA or RNA templates, and a ribonuclease H (RNase H) activity that cleaves the RNA strand of RNA-DNA heteroduplexes in a partially processive 3'- to 5'-endonucleasic mode. Neo-synthesized pregenomic RNA (pgRNA) are encapsidated together with the P protein, and reverse-transcribed inside the nucleocapsid. Initiation of reverse-transcription occurs first by binding the epsilon loop on the pgRNA genome, and is initiated by protein priming, thereby the 5'-end of (-)DNA is covalently linked to P protein. Partial (+)DNA is synthesized from the (-)DNA template and generates the relaxed circular DNA (RC-DNA) genome. After budding and infection, the RC-DNA migrates in the nucleus, and is converted into a plasmid-like covalently closed circular DNA (cccDNA). The activity of P protein does not seem to be necessary for cccDNA generation, and is presumably released from (+)DNA by host nuclear DNA repair machinery (By similarity). {ECO:0000250, ECO:0000269|PubMed:1380455, ECO:0000269|PubMed:2854056}.

FUNCTION: Multifunctional protein that plays a role in silencing host antiviral defenses and promoting viral transcription. Does not seem to be essential for HBV infection. May be directly involved in development of cirrhosis and liver cancer (hepatocellular carcinoma). Most of cytosolic activities involve modulation of cytosolic calcium. The effect on apoptosis is controversial depending on the cell types in which the studies have been conducted. May induce apoptosis by localizing in mitochondria and causing loss of mitochondrial membrane potential. May also modulate apoptosis by binding host CFLAR, a key regulator of the death-inducing signaling complex (DISC). Promotes viral transcription by using the host E3 ubiquitin ligase DDB1 to target the SMC5-SMC6 complex to proteasomal degradation. This host complex would otherwise bind to viral episomal DNA, and prevents its transcription. Moderately stimulates transcription of many different viral and cellular transcription elements. Promoters and enhancers stimulated by HBx contain DNA binding sites for NF-kappa-B, AP-1, AP-2, c-EBP, ATF/CREB, or the calcium-activated factor NF-AT. {ECO:0000255|HAMAP-Rule:MF_04074, ECO:0000269|PubMed:15767425}.

PTM: Sumoylated by host PML/nuclear domain 10 (By similarity). Sumoylation abolishes the interaction with host STAT2 and thus the IE1-mediated repression of interferon-stimulated genes (PubMed:18701593). {ECO:0000250|UniProtKB:P13202, ECO:0000269|PubMed:18701593}.

FUNCTION: Plays an important role in transactivating viral early genes as well as activating its own promoter, probably by altering the viral chromatin structure (PubMed:15572445, PubMed:17331553, PubMed:23878222, PubMed:26812545, PubMed:35138119, PubMed:8876134). Expression of IE1 and IE2 proteins is critical for the establishment of lytic infection and reactivation from viral latency (By similarity). Disrupts PML-associated ND10 nuclear bodies by interfering with host PML and SP100 sumoylation thereby altering the regulation of type I and type II interferon-induced gene expression (PubMed:10233977, PubMed:15163746, PubMed:17367754, PubMed:9151854). Promotes efficient viral growth by interacting with and directing host SP100 to degradation, leading to enhanced acetylation level of histones (PubMed:21880768). In addition, functions in counteracting the host innate antiviral response. Inhibits the type I interferon pathway by directly interacting with and sequestrating host STAT2 (PubMed:16497831, PubMed:18701593, PubMed:19812155). Also targets type II interferon pathway by repressing IL6- and STAT3 target genes (PubMed:27387064). Repression of STAT3 genes is due to STAT3 nuclear accumulation and disruption of IL6-induced STAT3 phosphorylation by IE1 (By similarity). This repression is followed by phosphorylation and activation of STAT1 (PubMed:27387064). Inhibits host ISG transcription by sequestering host ISGF3 in a PML- and STAT2- binding dependent manner (PubMed:25812002). Alters host cell cycle progression, probably through its interaction with host E2F1 or RB1 that overcomes the RB1-mediated repression of E2F-responsive promoters (PubMed:8892909). May act as a E3 ubiquitin ligase targeting several host proteins including HES1 and SP100A for ubiquitination and subsequent proteasomal degradation (PubMed:28750047). Impairs the radial migration of immature neurons by downregulating Gap junction alpha-1 protein/GJA1 also via ubiquitination and degradation (PubMed:37097169). {ECO:0000250|UniProtKB:P13202, ECO:0000269|PubMed:10233977, ECO:0000269|PubMed:15163746, ECO:0000269|PubMed:15572445, ECO:0000269|PubMed:16497831, ECO:0000269|PubMed:17331553, ECO:0000269|PubMed:17367754, ECO:0000269|PubMed:18701593, ECO:0000269|PubMed:19812155, ECO:0000269|PubMed:21880768, ECO:0000269|PubMed:23878222, ECO:0000269|PubMed:25812002, ECO:0000269|PubMed:26812545, ECO:0000269|PubMed:27387064, ECO:0000269|PubMed:28750047, ECO:0000269|PubMed:35138119, ECO:0000269|PubMed:37097169, ECO:0000269|PubMed:8876134, ECO:0000269|PubMed:8892909, ECO:0000269|PubMed:9151854}.

FUNCTION: Large tegument protein that plays multiple roles in the viral cycle. During viral entry, remains associated with the capsid while most of the tegument is detached and participates in the capsid transport toward the host nucleus. Plays a role in the routing of the capsid at the nuclear pore complex and subsequent uncoating. Within the host nucleus, acts as a deneddylase and promotes the degradation of nuclear CRLs (cullin-RING ubiquitin ligases) and thereby stabilizes nuclear CRL substrates, while cytoplasmic CRLs remain unaffected. These modifications prevent host cell cycle S-phase progression and create a favorable environment allowing efficient viral genome replication. Participates later in the secondary envelopment of capsids. Indeed, plays a linker role for the association of the outer viral tegument to the capsids together with the inner tegument protein (By similarity). Counteracts host TLR-mediated NF-kappa-B activation through both MYD88 and TICAM1-dependent pathways by interfering with 'Lys-63'- and 'Lys-48'-linked ubiquitination of signaling intermediates such as TRAF6 and IKBKG (PubMed:24586164). Inhibits type I interferon production by forming a tri-molecular complex with host TRIM25 and 14-3-3 thereby promoting TRIM25 autoubiquitination and sequestration of the ligase into inactive protein aggregates (PubMed:31710640). In turn, host RIGI is recruited to the complex but ubiquitination is severely impaired leading to inhibition of the pathway (PubMed:29357390). Catalyzes also the removal of 'Lys-48'- and 'Lys-63'-linked ubiquitin chains on host TBK1 and STING1 suppressing cGAS-STING signaling in addition to the RIGI-MAVS pathway (PubMed:36802409). Inhibits selective autophagy by deubiquitinating host SQSTM1. In turn, decreased SQSTM1 ubiquitination fails to recruit LC3 to SQSTM1-positive aggregates (PubMed:34543352). In the host nucleus, deubiquitinates topoisomerase II subunits TOP2A and TOP2B thereby stabilizing SUMOylated TOP2 which halts the DNA damage response to TOP2-induced double strand DNA breaks and promotes cell survival (PubMed:34543352). {ECO:0000255|HAMAP-Rule:MF_04044, ECO:0000269|PubMed:19244336, ECO:0000269|PubMed:20190741, ECO:0000269|PubMed:22474075, ECO:0000269|PubMed:24586164, ECO:0000269|PubMed:34543352, ECO:0000269|PubMed:36802409}.

Plays an essential role in the viral lytic DNA replication by acting as a polymerase accessory subunit (PubMed:16641300, PubMed:19801550). Stimulates the viral DNA polymerase activity and appears to function with it as a holoenzyme (PubMed:19801550). Increases the processivity of the viral polymerase, probably by acting as a sliding clamp that prevents dissociation of the polymerase from the active template (PubMed:19801550). In addition, BMRF1 transcriptionally activates the oriLyt early BHLF1 promoter (PubMed:8764021, PubMed:9126259). Promotes G1/S cell cycle arrest through p53 induction (PubMed:24501404). {ECO:0000269|PubMed:16641300, ECO:0000269|PubMed:19801550, ECO:0000269|PubMed:24501404, ECO:0000269|PubMed:31462557, ECO:0000269|PubMed:8764021, ECO:0000269|PubMed:9126259}.

FUNCTION: Transcription factor that acts as a molecular switch to induce the transition from the latent to the lytic or productive phase of the virus cycle (Probable) (PubMed:8404860). Mediates the switch from the latent to the lytic cycle of infection in cells containing a highly methylated viral genome (PubMed:15361873, PubMed:34893887). Probably binds to silenced chromatin and recruits host chromatin-remodeling enzymes (PubMed:30926617). Regulates this switch by binding to 2 types of ZEBRA response elements (ZREs): the CpG-free AP-1 like elements (latency) and the methylated CpG-containing elements (lytic replication) (Probable) (PubMed:22022468, PubMed:34893887). Activates preferentially the methylated forms of the viral lytic R (BRLF1) and Na (BRRF1) gene promoters, the latters being the first genes activated during Z-mediated reactivation in latently infected cells (PubMed:15361873, PubMed:19325883). BZLF1 and BRLF1 act together to trigger lytic replication (PubMed:10856251, PubMed:15361873). Also binds the lytic origin of replication, oriLyt (PubMed:20808903). Induces G1 cell cycle arrest by stabilizing the host CCAAT/enhancer binding protein CEBPA (PubMed:15078966). This function is important because the lytic cycle preferentially takes place in host cells arrested in G1 (PubMed:15078966). {ECO:0000269|PubMed:10856251, ECO:0000269|PubMed:15078966, ECO:0000269|PubMed:15361873, ECO:0000269|PubMed:17079287, ECO:0000269|PubMed:1847997, ECO:0000269|PubMed:19144704, ECO:0000269|PubMed:19325883, ECO:0000269|PubMed:20808903, ECO:0000269|PubMed:2157874, ECO:0000269|PubMed:22022468, ECO:0000269|PubMed:23678172, ECO:0000269|PubMed:30926617, ECO:0000269|PubMed:34893887, ECO:0000269|PubMed:8404860, ECO:0000305|PubMed:2157874}.

FUNCTION: Constitutively active, ligand-independent G protein-coupled receptor that has immunoevasive and oncogenic activities (PubMed:15596837, PubMed:15596846, PubMed:30647152, PubMed:34216564). Couples with the host inhibitory G protein (Gi) in order to disrupt the host chemokine signaling (PubMed:34216564). As a consequence of its constitutive activity, mediates host CXCR4 inhibition (PubMed:20622011). Enhances degradation of host major histocompatibility complex class I antigens via lysosomes, thereby modulating the antigen presentation to cytotoxic T cells (PubMed:19119421, PubMed:21123379, PubMed:23315076). Targets selectively HLA-A, HLA-Band HLA-E molecules (PubMed:23315076). Targets also newly synthesized MHC-I/peptide complexes en route to the host cell surface (PubMed:21123379). Inhibits the host EIF2AK2/PKR phosphorylation (PubMed:15596837). Displays tranforming activity (PubMed:20543866). Utilizes its C-terminal tail to trigger host MAVS UFMylation via PARK2, resulting in selective MAVS removal from mitochondrial membranes and routing to lysosomes to prevent viral activation of the NLRP3 inflammasome (PubMed:37311461). {ECO:0000269|PubMed:15596837, ECO:0000269|PubMed:15596846, ECO:0000269|PubMed:19119421, ECO:0000269|PubMed:20543866, ECO:0000269|PubMed:20622011, ECO:0000269|PubMed:21123379, ECO:0000269|PubMed:23315076, ECO:0000269|PubMed:30647152, ECO:0000269|PubMed:34216564, ECO:0000269|PubMed:37311461}.

FUNCTION: Responsible for the origin of replication (oriP) dependent replication and maintenance of viral episomes during latent infection (PubMed:15479791, PubMed:2996781). EBNA1 dimer interacts with the DS (dyad symmetry) element within the origin of replication oriP and with a host mitotic chromosome to initiate viral DNA replication during latency (PubMed:24067969, PubMed:2996781, PubMed:31142669, PubMed:8551585). EBNA1 binding to DS recruits the host origin recognition complex (ORC) (PubMed:12953058). Governs the faithful mitotic segregation of the viral episomes by binding both the FR (family of repeats) element within oriP and the host mitotic chromosomes (PubMed:11172042, PubMed:15479791, PubMed:24067969). Forms a cell cycle-dependent tyrosine-dependent DNA cross-link and single-strand cleavage at oriP required for terminating replication and maintaining viral episomes (PubMed:33482082). Counteracts the stabilization of host p53/TP53 by host USP7, thereby decreasing apoptosis and increasing host cell survival (PubMed:15808506). Induces degradation of host PML through the ubiquitin-proteasome system, which promotes lytic reactivation and may impair the host cell DNA repair (PubMed:18833293). Increases the association of CK2 with PML proteins which increases the phosphorylation of PML proteins by CK2, triggering the polyubiquitylation and degradation of PML (PubMed:20719947). Displays inhibitory effects on a SUMO2-modified complex that includes STUB1, KAP1 and USP7 (PubMed:32176739). This inhibitory effect possibly participates to the maintenance of latency linked to PML silencing (PubMed:32176739). {ECO:0000269|PubMed:11172042, ECO:0000269|PubMed:12953058, ECO:0000269|PubMed:15479791, ECO:0000269|PubMed:15808506, ECO:0000269|PubMed:18833293, ECO:0000269|PubMed:20719947, ECO:0000269|PubMed:24067969, ECO:0000269|PubMed:2996781, ECO:0000269|PubMed:31142669, ECO:0000269|PubMed:32176739, ECO:0000269|PubMed:33482082, ECO:0000269|PubMed:8551585}.

FUNCTION: Acts as a CD40 functional homolog to prevent apoptosis of infected B-lymphocytes and drive their proliferation. Functions as a constitutively active tumor necrosis factor receptor that induces the activation of several signaling pathways, including those of the NF-kappa-B family. LMP1 signaling leads to up-regulation of antiapoptotic proteins and provide growth signals in latently infected cells. Interacts with host UBE2I and subsequently affects the sumoylation state of several cellular proteins. For example, induces the sumoylation of host IRF7 thereby limiting its transcriptional activity and modulating the activation of innate immune responses. Inhibits also host IFN-alpha-stimulated STAT2 nuclear translocation and interferon-stimulated response element transcriptional activity by interacting with and inhibiting host TYK2. Induces SUMO expression during viral latency thereby dysregulating the host sumoylation processes (PubMed:30659232). {ECO:0000269|PubMed:16987978, ECO:0000269|PubMed:19017798, ECO:0000269|PubMed:21795333, ECO:0000269|PubMed:22951831, ECO:0000269|PubMed:30659232}.

PTM: Capsid scaffolding protein is cleaved by assemblin after formation of the spherical procapsid. As a result, the capsid obtains its mature, icosahedral shape. Cleavages occur at two or more sites: release and tail site. {ECO:0000255|HAMAP-Rule:MF_04008}.
SUBCELLULAR LOCATION: [Capsid scaffolding protein]: Host cytoplasm {ECO:0000255|HAMAP-Rule:MF_04008}.; SUBCELLULAR LOCATION: [Assemblin]: Host nucleus {ECO:0000255|HAMAP-Rule:MF_04008}.; SUBCELLULAR LOCATION: [Assembly protein]: Host nucleus {ECO:0000255|HAMAP-Rule:MF_04008}.; SUBCELLULAR LOCATION: [Isoform pAP]: Host nucleus {ECO:0000269|PubMed:30710799}.
CATALYTIC ACTIVITY: Reaction=Cleaves -Ala-|-Ser- and -Ala-|-Ala- bonds in the scaffold protein.; EC=3.4.21.97; Evidence={ECO:0000255|HAMAP-Rule:MF_04008};

FUNCTION: [Capsid scaffolding protein]: Acts as a scaffold protein by binding major capsid protein in the cytoplasm, inducing the nuclear localization of both proteins. Multimerizes in the nucleus such as major capsid protein forms the icosahedral T=16 capsid. Autocatalytic cleavage releases the assembly protein, and subsequently abolishes interaction with major capsid protein. Cleavages products are evicted from the capsid before or during DNA packaging. {ECO:0000255|HAMAP-Rule:MF_04008, ECO:0000269|PubMed:19158247}.; FUNCTION: [Assemblin]: Protease that plays an essential role in virion assembly within the nucleus. Catalyzes the cleavage of the assembly protein after formation of the spherical procapsid. By that cleavage, the capsid matures and gains its icosahedral shape. The cleavage sites seem to include -Ala-Ser-, -Ala-Ala-, as well as Ala-Thr bonds. Assemblin and cleavages products are evicted from the capsid before or during DNA packaging. {ECO:0000255|HAMAP-Rule:MF_04008, ECO:0000269|PubMed:19158247}.; FUNCTION: [Assembly protein]: Plays a major role in capsid assembly. Acts as a scaffold protein by binding major capsid protein. Multimerizes in the nucleus such as major capsid protein forms the icosahedral T=16 capsid. Cleaved by assemblin after capsid completion. The cleavages products are evicted from the capsid before or during DNA packaging. {ECO:0000255|HAMAP-Rule:MF_04008, ECO:0000269|PubMed:19158247}.

FUNCTION: Plays a major role to prevent cellular inhibition of viral genome replication (PubMed:12186903, PubMed:14657032, PubMed:18614635, PubMed:20484509, PubMed:20861261, PubMed:25772236).

This viral RING-type ligase ubiquitinates cellular substrates and targets them to proteasomal degradation: TP53/p53, LIG4, MRE11-RAD50-NBS1 (MRN) complex, ITGA3, DAXX and BLM (PubMed:12186903, PubMed:18614635, PubMed:20484509).

FUNCTION: Cleaves viral precursor proteins (pTP, pIIIa, pVI, pVII, pVIII, and pX) inside newly assembled particles giving rise to mature virions. Protease complexed to its cofactor slides along the viral DNA to specifically locate and cleave the viral precursors. Mature virions have a weakened organization compared to the unmature virions, thereby facilitating subsequent uncoating. Without maturation, the particle lacks infectivity and is unable to uncoat. Late in adenovirus infection, in the cytoplasm, may participate in the cytoskeleton destruction. Cleaves host cell cytoskeletal keratins K7 and K18. {ECO:0000255|HAMAP-Rule:MF_04059, ECO:0000269|PubMed:22791715}.

FUNCTION: Plays a role in viral genome replication by driving entry of quiescent cells into the cell cycle. Stimulation of progression from G1 to S phase allows the virus to efficiently use the cellular DNA replicating machinery to achieve viral genome replication. E1A protein has both transforming and trans-activating activities. Induces the disassembly of the E2F1 transcription factor from RB1 by direct competition for the same binding site on RB1, with subsequent transcriptional activation of E2F1-regulated S-phase genes and of the E2 region of the adenoviral genome. Release of E2F1 leads to the ARF-mediated inhibition of MDM2 and causes TP53/p53 to accumulate because it is not targeted for degradation by MDM2-mediated ubiquitination anymore. This increase in TP53, in turn, would arrest the cell proliferation and direct its death but this effect is counteracted by the viral protein E1B-55K. Inactivation of the ability of RB1 to arrest the cell cycle is critical for cellular transformation, uncontrolled cellular growth and proliferation induced by viral infection. Interaction with RBX1 and CUL1 inhibits ubiquitination of the proteins targeted by SCF(FBXW7) ubiquitin ligase complex, and may be linked to unregulated host cell proliferation. The tumorigenesis-restraining activity of E1A may be related to the disruption of the host CtBP-CtIP complex through the CtBP binding motif. Interacts with host TBP protein; this interaction probably disrupts the TBP-TATA complex. Interaction with host TMEM173/STING impairs the ability of TMEM173/STING to sense cytosolic DNA and promote the production of type I interferon (IFN-alpha and IFN-beta). Promotes the sumoylation of host ZBED1/hDREF with SUMO1 (By similarity). {ECO:0000250|UniProtKB:P03255}.

FUNCTION: Plays a role in the elongation phase of viral strand displacement replication by unwinding the template in an ATP-independent fashion, employing its capacity to form multimers. Also enhances the rate of initiation. Released from template upon second strand synthesis. Assembles in complex with viral pTP, viral pol, host NFIA and host POU2F1/OCT1 on viral origin of replication. Covers the whole ssDNA genome during synthesis.
