https://en.wikipedia.org/wiki/KLC1
Kinesin light chain 1 is a protein that in humans is encoded by the KLC1 gene. Conventional kinesin is a tetrameric molecule composed of two heavy chains and two light chains, and transports various cargos along microtubules toward their plus ends. The heavy chains provide the motor activity, while the light chains bind to various cargos. This gene encodes a member of the kinesin light chain family. It associates with kinesin heavy chain through an N-terminal domain, and six tetratricopeptide repeat (TPR) motifs are thought to be involved in binding of cargos such as vesicles, mitochondria, and the Golgi complex. Thus, kinesin light chains function as adapter molecules and not motors per se. Although previously named "kinesin 2", this gene is not a member of the kinesin-2 / kinesin heavy chain subfamily of kinesin motor proteins. Extensive alternative splicing produces isoforms with different C-termini that are proposed to bind to different cargos; however, the full-length nature of some of these variants has not been determined. Interactions KLC1 has been shown to interact with MAPK8IP3, KIF5B and KIF5A. References Further reading
https://en.wikipedia.org/wiki/Laminin%2C%20beta%202
Laminin subunit beta-2 is a protein that in humans is encoded by the LAMB2 gene. Function Laminins, a family of extracellular matrix glycoproteins, are the major noncollagenous constituent of basement membranes. They have been implicated in a wide variety of biological processes including cell adhesion, differentiation, migration, signaling, neurite outgrowth and metastasis. Laminins are composed of 3 non identical chains: laminin alpha, beta and gamma (formerly A, B1, and B2, respectively) and they form a cruciform structure consisting of 3 short arms, each formed by a different chain, and a long arm composed of all 3 chains. Each laminin chain is a multidomain protein encoded by a distinct gene. Several isoforms of each chain have been described. Different alpha, beta and gamma chain isomers combine to give rise to different heterotrimeric laminin isoforms, which were formerly designated by Arabic numerals in the order of their discovery, e.g. alpha1beta1gamma1 heterotrimer was known as laminin 1, but the nomenclature now calls for using the numbers of each individual laminin subunit isoform, e.g. what was formerly Laminin 1 is now Laminin 111, and what was formerly Laminin 5 is now Laminin 332. The biological functions of the different chains and trimer molecules are largely unknown, but some of the chains have been shown to differ with respect to their tissue distribution, presumably reflecting diverse functions in vivo. This gene encodes the beta chain isoform
https://en.wikipedia.org/wiki/Galectin-8
Galectin-8 is a protein of the galectin family that in humans is encoded by the LGALS8 gene. Function This gene encodes a member of the galectin family. Galectins are beta-galactoside-binding animal lectins with conserved carbohydrate recognition domains. The galectins have been implicated in many essential functions including development, differentiation, cell-cell adhesion, cell-matrix interaction, growth regulation, apoptosis, and RNA splicing. This gene is widely expressed in tumoral tissues and seems to be involved in integrin-like cell interactions. Alternatively spliced transcript variants encoding different isoforms have been identified. Galectin-8, interacts with the mTOR regulatory system composed of SLC38A9, Ragulator, RagAB, RagCD. Galectin-8 controls mTOR causing its inactivation and dissociation from damaged lysosomes, hence transducing the breach of the lysosomal membrane to mTOR. The physiological consequences of mTOR inhibition following lysosomal membrane damage encompass autophagy and metabolic switching. Role in cellular defence Galectin-8 has recently been shown to have a role in cellular defence, against both bacterial cytosolic infection and vacuolar damage. Many intracellular bacteria, such as S. enterica serovar Typhimurium and S. flexneri prefer to replicate inside and outside of the vacuole safety respectively, yet these vacuoles may become damaged, exposing bacteria to the host cell cytoplasm. It has been shown that the binding of galectin

LIM and senescent cell antigen-like-containing domain protein 1 is a protein that in humans is encoded by the LIMS1 gene. Function The protein encoded by this gene is an adaptor protein which contains five LIM domains, or double zinc fingers. The protein is likely involved in integrin signaling through its LIM domain-mediated interaction with integrin-linked kinase, found in focal adhesion plaques. It is also thought to act as a bridge linking integrin-linked kinase to NCK adaptor protein 2, which is involved in growth factor receptor kinase signaling pathways. Its localization to the periphery of spreading cells also suggests that this protein may play a role in integrin-mediated cell adhesion or spreading. Interactions LIMS1 has been shown to interact with Integrin-linked kinase and NCK2. References Further reading

https://en.wikipedia.org/wiki/MAGEA4
Melanoma-associated antigen 4 is a protein that in humans is encoded by the MAGEA4 gene. This gene is a member of the MAGEA gene family. The members of this family encode proteins with 50 to 80% sequence identity to each other. The promoters and first exons of the MAGEA genes show considerable variability, suggesting that the existence of this gene family enables the same function to be expressed under different transcriptional controls. Clinical importance The MAGEA genes are clustered at chromosomal location Xq28. They have been implicated in some hereditary disorders, such as dyskeratosis congenita. At least four variants encoding the same protein have been found for this gene. In salivary gland carcinomas, MAGE4 expression correlates to lower-grade histology, lower likelihood of metastases and more favourable survival. While MAGEA4 is expressed by many tumours, it is almost universally expressed by synovial sarcomas.

Milk fat globule-EGF factor 8 protein (Mfge8), also known as lactadherin, is a protein that in humans is encoded by the MFGE8 gene. Species distribution Mfge8 is a secreted protein found in vertebrates, including mammals as well as birds. Function MFGE8 may function as a cell adhesion protein to connect smooth muscle to elastic fibers in arteries. An amyloid fragment of MFGE8 known as medin accumulates in the aorta with aging. MFGE8 in the vasculature of adults can induce recovery from ischemia by facilitating angiogenesis. It has been suggested that antagonizing MFGE8-induced angiogenesis could be a way of fighting cancer. MFGE8 contains a phosphatidylserine (PS) binding domain, as well as an arginine-glycine-aspartic acid motif, which enables the binding to integrins. MFGE8 binds PS, which is exposed on the surface of apoptotic cells. Opsonization of the apoptotic cells and binding to integrins on the surface of phagocytic cells, mediates the engulfment of the dead cell. References Further reading

https://en.wikipedia.org/wiki/MTHFD1
MTHFD1 is a gene located in humans on chromosome 14 that encodes for a protein with three distinct enzymatic activities. C-1-tetrahydrofolate synthase, cytoplasmic also known as C1-THF synthase is an enzyme that in humans is encoded by the MTHFD1 (methylenetetrahydrofolate dehydrogenase 1) gene. Function This gene encodes a protein that possesses three distinct enzymatic activities, methylenetetrahydrofolate dehydrogenase (1.5.1.5), methenyltetrahydrofolate cyclohydrolase (3.5.4.9) and formate–tetrahydrofolate ligase (6.3.4.3). Each of these activities catalyzes one of three sequential reactions in the interconversion of 1-carbon derivatives of tetrahydrofolate, which are substrates for methionine, thymidylate, and de novo purine syntheses. The trifunctional enzymatic activities are conferred by two major domains, an aminoterminal portion containing the dehydrogenase and cyclohydrolase activities and a larger synthetase domain. Clinical significance Mutations of the MTHFD1 gene may cause methylenetetrahydrofolate dehydrogenase 1 deficiency, also known as combined immunodeficiency and megaloblastic anemia with or without hyperhomocysteinemia (CIMAH).

Myosin heavy chain, α isoform (MHC-α) is a protein that in humans is encoded by the MYH6 gene. This isoform is distinct from the ventricular/slow myosin heavy chain isoform, MYH7, referred to as MHC-β. MHC-α isoform is expressed predominantly in human cardiac atria, exhibiting only minor expression in human cardiac ventricles. It is the major protein comprising the cardiac muscle thick filament, and functions in cardiac muscle contraction. Mutations in MYH6 have been associated with late-onset hypertrophic cardiomyopathy, atrial septal defects and sick sinus syndrome. Structure MHC-α is a 224 kDa protein composed of 1939 amino acids. The MYH6 gene is located on chromosome 14q12, approximately ~4kb downstream of the MYH7 gene encoding the other major cardiac muscle isoform of myosin heavy chain, MHC-β. MHC-α is a hexameric, asymmetric motor forming the bulk of the thick filament in cardiac muscle; it is the predominant isoform expressed in human cardiac atria, and the lesser expressed isoform (7%) expressed in human cardiac ventricles. MHC-α is composed of N-terminal globular heads (20 nm) that project laterally, and alpha helical tails (130 nm) that dimerize and multimerize into a coiled-coil motif to form the light meromyosin (LMM), thick filament rod. The 9 nm alpha-helical neck region of each MHC-α head non-covalently binds two light chains, atrial essential light chain (MYL4) and atrial regulatory light chain (MYL7).

Sodium/potassium-transporting ATPase subunit alpha-3 is an enzyme that in humans is encoded by the ATP1A3 gene. Function The protein encoded by this gene belongs to the family of P-type cation transport ATPases, and to the subfamily of Na+/K+-ATPases. Na+/K+-ATPase is an integral membrane protein responsible for establishing and maintaining the electrochemical gradients of Na and K ions across the plasma membrane. These gradients are essential for osmoregulation, for sodium-coupled transport of a variety of organic and inorganic molecules, and for electrical excitability of nerve and muscle.

V-type proton ATPase 16 kDa proteolipid subunit is an enzyme that in humans is encoded by the ATP6V0C gene. Function This gene encodes a component of vacuolar ATPase (V-ATPase), a multisubunit enzyme that mediates acidification of eukaryotic intracellular organelles. V-ATPase dependent organelle acidification is necessary for such intracellular processes as protein sorting, zymogen activation, receptor-mediated endocytosis, and synaptic vesicle proton gradient generation. V-ATPase is composed of a cytosolic V1 domain and a transmembrane V0 domain. The V1 domain consists of three A and three B subunits, two G subunits plus the C, D, E, F, and H subunits. The V1 domain contains the ATP catalytic site. The V0 domain consists of five different subunits: a, c, c', c", and d.

Nuclear transcription factor Y subunit gamma is a protein that in humans is encoded by the NFYC gene. Function The protein encoded by this gene is one subunit of a trimeric complex, forming a highly conserved transcription factor that binds with high specificity to CCAAT motifs in the promoter regions in a variety of genes. This gene product, subunit C, forms a tight dimer with the B subunit (NFYB), a prerequisite for subunit A (NFYA) association. The resulting trimer binds to DNA with high specificity and affinity. Subunits B and C each contain a histone-like motif. Observation of the histone nature of these subunits is supported by two types of evidence; protein sequence alignments and experiments with mutants. Additional regulation, preliminarily supported by the EST database, may be represented by alternative splicing in this subunit. Two microRNAs; miR-30c and miR-30e are located within introns of the nfyc gene. These microRNAs are actively transcribed in human insulin-producing beta cells in the pancreatic islets that also show high expression of nfyc and CDH1 genes. The expression of these intronic microRNAs is essential for maintaining the differentiated phenotype of human islet beta cells. Inhibition of miR-30 family microRNAs induces epithelial-mesenchymal transition of human pancreatic islet cells. Interactions NFYC has been shown to interact with Myc.

NADH dehydrogenase [ubiquinone] 1 alpha subcomplex subunit 13 is an enzyme that in humans is encoded by the NDUFA13 gene. The NDUFA13 protein is a subunit of NADH dehydrogenase (ubiquinone), which is located in the mitochondrial inner membrane and is the largest of the five complexes of the electron transport chain. Structure The NDUFA13 gene is located on the p arm of chromosome 19 in position 13.2 and spans 11,995 base pairs. The gene produces a 17 kDa protein composed of 144 amino acids. NDUFA13 is a subunit of the enzyme NADH dehydrogenase (ubiquinone), the largest of the respiratory complexes. The structure is L-shaped with a long, hydrophobic transmembrane domain and a hydrophilic domain for the peripheral arm that includes all the known redox centers and the NADH binding site. It has been noted that the N-terminal hydrophobic domain has the potential to be folded into an alpha helix spanning the inner mitochondrial membrane with a C-terminal hydrophilic domain interacting with globular subunits of Complex I.

The Abelson helper integration site 1 (AHI1) is a protein coding gene that is known for the critical role it plays in brain development. Proper cerebellar and cortical development in the human brain depends heavily on AHI1. The AHI1 gene is prominently expressed in the embryonic hindbrain and forebrain. AHI1 specifically encodes the Jouberin protein and mutations in the expression of the gene is known to cause specific forms of Joubert syndrome. Joubert syndrome is autosomal recessive and is characterized by the brain malformations and mental retardation that AHI1 mutations have the potential to induce. AHI1 has also been associated with schizophrenia and autism due to the role it plays in brain development. An AHI1 heterozygous knockout mouse model was studied by Bernard Lerer and his group at Hadassah Medical Center in Jerusalem to elucidate the correlation between alterations in AHI1 expression and the pathogenesis of neuropsychiatric disorders. The core temperatures and corticosterone secretions of the heterozygous knockout mice after exposure to environmental and visceral stress exhibited extreme repression of autonomic nervous system and hypothalamic-pituitary-adrenal responses. The knockout mice demonstrated an increased resilience to different types of stress and these results lead to a correlation between emotional regulation and neuropsychiatric disorders.

Vacuolar protein sorting ortholog 35 (VPS35) is a protein involved in autophagy and is implicated in neurodegenerative diseases, such as Parkinson's disease (PD) and Alzheimer's disease (AD). VPS35 is part of a complex called the retromer, which is responsible for transporting select cargo proteins between vesicular structures (e.g., endosomes, lysosomes, vacuoles) and the Golgi apparatus. Mutations in the VPS35 gene (VPS35) cause aberrant autophagy, where cargo proteins fail to be transported and dysfunctional or unnecessary proteins fail to be degraded. There are numerous pathways affected by altered VPS35 levels and activity, which have clinical significance in neurodegeneration. There is therapeutic relevance for VPS35, as interventions aimed at correcting VPS35 function are in speculation. Gene In humans, VPS35 is transcribed on chromosome 16q11.2 where is spans about 29.6 kilobases and contains 17 exons. It is evolutionarily conserved and required for survival, as mouse knockout studies have demonstrated embryonic lethality. VPS35 levels peak at postnatal days 10-15 and then decline to a low, stable level throughout adulthood. RNA expression of VPS35 is ubiquitous throughout the body, but are higher in the brain, heart, gonads, spleen, and skeletal muscle, and lower in the lung, liver, kidney, and blood leukocytes.

Many theorems about finitely generated modules over Noetherian rings can be extended to finitely presented modules over coherent rings. Every left Noetherian ring is left coherent. The ring of polynomials in an infinite number of variables over a left Noetherian ring is an example of a left coherent ring that is not left Noetherian. A ring is left coherent if and only if every direct product of flat right modules is flat , . Compare this to: A ring is left Noetherian if and only if every direct sum of injective left modules is injective. References Ring theory

Actin, gamma-enteric smooth muscle is a protein that in humans is encoded by the ACTG2 gene. Actins are highly conserved proteins that are involved in various types of cell motility, and maintenance of the cytoskeleton. In vertebrates, three main groups of actin isoforms, alpha, beta and gamma have been identified. The alpha actins are found in muscle tissues and are a major constituent of the contractile apparatus. The beta and gamma actins co-exist in most cell types as components of the cytoskeleton, and as mediators of internal cell motility. Actin, gamma 2, encoded by this gene, is a smooth muscle actin found in enteric tissues. Interactions ACTG2 has been shown to interact with Emerin.

Lysine-specific demethylase 5A is an enzyme that in humans is encoded by the KDM5A gene. Function The protein encoded by this gene is a ubiquitously expressed nuclear protein. It binds directly, with several other proteins, to retinoblastoma protein which regulates cell proliferation. It was formerly known as Retinoblastoma Binding Protein 2 (RBP2). This protein also interacts with rhombotin-2 which functions distinctly in erythropoiesis and in T-cell leukemogenesis. Rhombotin-2 is thought to either directly affect the activity of the encoded protein or may indirectly modulate the functions of the retinoblastoma protein by binding to this protein. Alternatively spliced transcript variants encoding distinct isoforms have been found for this gene. The Drosophila homolog, LID, was found to be an H3K4 histone demethylase that binds to c-Myc. It was recently renamed to Lysine Demethylase 5 (KDM5). Enzymatically can be designated as a trimethyllysine dioxygenase, which is a member of the alpha-ketoglutarate-dependent hydroxylase superfamily ().

Roundabout homolog 1 is a protein that in humans is encoded by the ROBO1 gene. Function Bilateral symmetric nervous systems have special midline structures that establish a partition between the two mirror image halves. Some axons project toward and across the midline in response to long-range chemoattractants emanating from the midline. The protein encoded by ROBO1 is structurally similar to a Drosophila integral membrane protein which is encoded by the Drosophila roundabout gene (a member of the immunoglobulin gene superfamily) and is both an axon guidance receptor and a cell adhesion receptor, known to be involved in the decision by axons to cross the central nervous system midline. Two transcript variants encoding different isoforms have been found for ROBO1. Clinical significance ROBO1 was implicated in a communication disorder based on a Finnish pedigree with severe dyslexia. Analyses revealed a translocation had occurred disrupting ROBO1. Study of the phonological memory component of the language acquisition system suggests that ROBO1 polymorphisms are associated with functioning in this system.

The T-box gene family consists of 17 members in mouse and humans that are grouped into five subfamilies, namely Brachyury (T), T-brain (Tbr1), TBX1, TBX2, and TBX6. Tbx3 is a member of the Tbx2 subfamily which includes Tbx2, Tbx4 and Tbx5. The human TBX3 gene maps to chromosome 12 at position 12q23-24.1 and consists of 7 exons which encodes a 723 amino acid protein (ENSEMBL assembly release GRCh38.p12). Transcript splicing Alternative processing and splicing results in at least 4 distinct TBX3 isoforms with TBX3 and TBX3+2a being the predominant isoforms. TBX3+2a results from alternative splicing of the second intron which leads to the addition of the +2a exon and consequently this isoform has an additional 20 amino acids within the T-box DNA binding domain.

Nicotinamide mononucleotide adenylyltransferase 1 (NMNAT1) is an enzyme that in humans is encoded by the nmnat1 gene. It is a member of the nicotinamide-nucleotide adenylyltransferases (NMNATs) which catalyze nicotinamide adenine dinucleotide (NAD) synthesis. Function The coenzyme NAD and its derivatives are involved in hundreds of metabolic redox reactions and are utilized in protein ADP-ribosylation, histone deacetylation, and in some Ca2+ signaling pathways. NMNAT (EC 2.7.7.1) is a central enzyme in NAD biosynthesis, catalyzing the condensation of nicotinamide mononucleotide (NMN) or nicotinic acid mononucleotide (NaMN) with the AMP moiety of ATP to form NAD or NaAD. NMNAT1 is the most widely expressed of three orthologous genes with nicotinamide-nucleotide adenylyltransferase (NMNAT) activity. Genetically engineered mice lacking NMNAT1 die during early embryogenesis, indicating a critical role of this gene in organismal viability. In contrast, mice lacking NMNAT2, which is expressed predominantly in neural tissues, complete development but die shortly after birth. However, NMNAT1 is dispensable for cell viability, as homozygous deletion of this gene occurs in glioblastoma tumors and cell lines. Other tumors such as osteosarcoma, however, increase the expression of NMNAT1 upon exposure to DNA damaging agents and inactivation of the nmnat1 gene renders these cells more sensitive to chemotherapy with cisplatin. This latter effect involves lowered nuclear NAD levels in N

Regulator of nonsense transcripts 3B is a protein that in humans is encoded by the UPF3B gene. This gene encodes a protein that is part of a post-splicing multiprotein complex involved in both mRNA nuclear export and mRNA surveillance. The encoded protein is one of two functional homologs to yeast Upf3p. mRNA surveillance detects exported mRNAs with truncated open reading frames and initiates nonsense-mediated mRNA decay (NMD). When translation ends upstream from the last exon-exon junction, this triggers NMD to degrade mRNAs containing premature stop codons. This protein binds to the mRNA and remains bound after nuclear export, acting as a nucleocytoplasmic shuttling protein. It forms with Y14 a complex that binds specifically 20 nt upstream of exon-exon junctions. This gene is located on the long arm of chromosome X.

Alternatively spliced transcript variants have been found for this gene. Function Carbonyl reductase is one of several monomeric, NADPH-dependent oxidoreductases having wide specificity for carbonyl compounds. This enzyme is widely distributed in human tissues. Another carbonyl reductase gene, CBR3, lies close to this gene on chromosome 21q22.12. CBR1 metabolizes many toxic environmental quinones and pharmacological relevant substrates such as the anticancer doxorubicin. Several studies have shown that CBR1 plays a protective role in oxidative stress, neurodegeneration, and apoptosis. In addition, CBR1 inactivates lipid aldehydes during oxidative stress in cells. Therefore, CBR1 may play a beneficial role in protecting against cellular damage resulting from oxidative stress. Polymorphisms Up-to-date two non-synonymous polymorphisms on CBR1 have been identified. The CBR1 V88I polymorphism encodes for a valine-to-isoleucine substitution at position 88 of the aminoacid chain.

This gene encodes a 28S subunit protein of the mitochondrial ribosome (mitoribosome) and plays key roles in translation, cellular respiration, and apoptosis. Moreover, DAP3 is associated with cancer development, but has been observed to aid some cancers while suppressing others. Structure The DAP3 gene encodes a 46 kDa protein located in the lower area of the small mitoribosomal subunit. This protein contains a P-loop motif that binds GTP and a highly conserved 17-residue targeting sequence responsible for its localization to the mitochondria. Of interest, many of the phosphorylation sites on this protein are highly conserved and clustered around GTP-binding motifs. Several splice variants were observed in human ESTs that differ largely in the 5’ UTR region. Pseudogenes for this gene are also found in chromosomes 1 and 2. Function DAP3 is a 28S subunit protein of mitoribosomes and localizes to the mitochondrial matrix. As part of the mitoribosome, DAP3 participates in the translation of the 13 ETC complex proteins encoded in the mitochondrial genome, and consequently, in the regulation of cellular respiration.

DNA repair and recombination protein RAD54-like is a protein that in humans is encoded by the RAD54L gene. The protein encoded by this gene belongs to the DEAD-like helicase superfamily, and shares similarity with Saccharomyces cerevisiae Rad54, a protein known to be involved in the homologous recombination and repair of DNA. This protein has been shown to play a role in homologous recombination related repair of DNA double-strand breaks. The binding of this protein to double-strand DNA induces a DNA topological change, which is thought to facilitate homologous DNA pairing, and stimulate DNA recombination. RAD54 is one of the key proteins necessary for homologous recombination and DNA repair in many organisms. Without functional RAD54, tumor development is more likely. RAD54 was initially described in the budding yeast Saccharomyces cerevisiae as being a member of the evolutionarily conserved RAD52 epistasis group, which additionally includes RAD51, RAD52, RAD55, and RAD57 factors. This group is believed to be involved in DNA recombination events and repair mechanisms, especially those involving double-stranded DNA breaks during both mitosis and meiosis.

https://en.wikipedia.org/wiki/VAPB
Vesicle-associated membrane protein-associated protein B/C is a protein that in humans is encoded by the VAPB gene. The VAPB gene is found on the 20th human chromosome. Together with VAPA, it forms the VAP protein family. Function The protein encoded by this gene is a type IV membrane protein found in plasma and intracellular vesicle membranes. The encoded protein is found as a homodimer and as a heterodimer with VAPA. This protein also can interact with VAMP1 and VAMP2 and may be involved in vesicle trafficking. Like VAPA, VAPB binds to proteins that contain a FFAT motif. Considerable interest in VAPB has arisen because mutations in this protein are associated with rare, familial forms of motor neuron disease (also called amyotrophic lateral sclerosis and Lou Gehrig's disease).

https://en.wikipedia.org/wiki/MYOT
Myotilin is a protein that in humans is encoded by the MYOT gene. Myotilin (myofibrillar titin-like protein) also known as TTID (TiTin Immunoglobulin Domain) is a muscle protein that is found within the Z-disc of sarcomeres. Structure Myotilin is a 55.3 kDa protein composed of 496 amino acids. Myotilin was originally identified as a novel alpha-actinin binding partner with two Ig-like domains, that localized to the Z-disc. The I-type Ig-like domains reside at the C-terminal half, and are most homologous to Ig domains 2-3 of palladin and Ig domains 4-5 of myopalladin and more distantly related to Z-disc Ig domains 7 and 8 of titin. The C-terminal region hosts the binding sites for Z-band proteins, and 2 Ig domains are the site of homodimerization for myotilin. By contrast, the N-terminal part of myotilin is unique, consisting of a serine-rich region with no homology to known proteins. Several disease-associated mutations involve serine residues within the serine-rich domain. Myotilin expression in human tissues is mainly restricted to striated muscles and nerves. In muscles, myotilin is predominantly found within the Z-discs. Myotilin forms homodimers and binds alpha-actinin, actin, Filamin C, FATZ-1, FATZ-2 and ZASP. Function Myotilin is a structural protein that, along with titin and alpha-actinin give structural integrity to sarcomeres at Z-discs in striated muscle. Myotilin induces the formation of actin bundles in vitro and in non-muscle cells. A ternary complex myotil

https://en.wikipedia.org/wiki/ARHGEF11
Rho guanine nucleotide exchange factor 11 is a protein that in humans is encoded by the ARHGEF11 gene. This protein is also called RhoGEF11 or PDZ-RhoGEF. Function Rho guanine nucleotide exchange factor 11 is guanine nucleotide exchange factor (GEF) for the RhoA small GTPase protein. Rho is a small GTPase protein that is inactive when bound to the guanine nucleotide GDP. But when acted on by Rho GEF proteins such as RhoGEF1, this GDP is released and replaced by GTP, leading to the active state of Rho. In this active, GTP-bound conformation, Rho can bind to and activate specific effector proteins and enzymes to regulate cellular functions. In particular, active Rho is a major regulator of the cell actin cytoskeleton. RhoGEF11 is a member of a group of four RhoGEF proteins known to be activated by G protein coupled receptors coupled to the G12 and G13 heterotrimeric G proteins. The others are ARHGEF1 (also known as p115-RhoGEF), ARHGEF12 (also known as LARG) and AKAP13 (also known as ARHGEF13 and Lbc). GPCR-regulated RhoGEF11 (and these related GEF proteins) acts as an effector for G12 and G13 G proteins. In addition to being activated by G12 or G13 G proteins, three of these four RhoGEF proteins (ARHGEF1/11/12) also function as RGS family GTPase-activating proteins (GAPs) to increase the rate of GTP hydrolysis of G12/G13 alpha proteins (which are themselves GTPase proteins). This action increases the rate of G protein deactivation, limiting the time during which these Rho

https://en.wikipedia.org/wiki/BIRC7
Baculoviral IAP repeat-containing protein 7 is a protein that in humans is encoded by the BIRC7 gene. The protein encoded by this gene is a member of the family of inhibitor of apoptosis proteins (IAP) and contains a single copy of a baculovirus IAP repeat (BIR) as well as a RING-type zinc finger domain. The BIR domain is essential for inhibitory activity and interacts with caspases, while the RING finger domain sometimes enhances antiapoptotic activity but does not inhibit apoptosis alone. Two transcript variants encoding different isoforms have been found for this gene. The two isoforms have different antiapoptotic properties, with isoform alpha protecting cells from apoptosis induced by staurosporine and isoform b protecting cells from apoptosis induced by etoposide. In melanoma, BIRC7 gene expression is regulated by the Microphthalmia-associated transcription factor. References External links Further reading
https://en.wikipedia.org/wiki/MAP1LC3B
Microtubule-associated proteins 1A/1B light chain 3B (hereafter referred to as LC3) is a protein that in humans is encoded by the MAP1LC3B gene. LC3 is a central protein in the autophagy pathway where it functions in autophagy substrate selection and autophagosome biogenesis. LC3 is the most widely used marker of autophagosomes. Discovery LC3 was originally identified as a microtubule associated protein in rat brain. However it was later found that the primary function of LC3 is in autophagy, a process that involves the bulk degradation of cytoplasmic components. The ATG8 protein family MAP1LC3B is a member of the highly conserved ATG8 protein family. ATG8 proteins are present in all known eukaryotic organisms. The animal ATG8 family comprises three subfamilies: (i) microtubule-associated protein 1 light chain 3 (MAP1LC3); (ii) Golgi-associated ATPase enhancer of 16 kDa (GATE-16); and (iii) γ-amino-butyric acid receptor-associate protein (GABARAP). MAP1LC3B is one of the four genes in the MAP1LC3 subfamily (others include MAP1LC3A, MAP1LC3C, and MAP1LC3B2). Function Cytoplasmic LC3 Newly synthesized LC3's C-terminus is hydrolyzed by a cysteine protease called ATG4B exposing Gly120, termed LC3-I. LC3-I, through a series of ubiquitin-like reactions involving enzymes ATG7, ATG3, and ATG12-ATG5-ATG16, becomes conjugated to the head group of the lipid phosphatidylethanolamine. The lipid modified form of LC3, referred to as LC3-II, is believed to be involved in autophagos
https://en.wikipedia.org/wiki/BRIP1
Fanconi anemia group J protein is a protein that in humans is encoded by the BRCA1-interacting protein 1 (BRIP1) gene. Function The protein encoded by this gene is a member of the RecQ DEAH helicase family and interacts with the BRCT repeats of breast cancer, type 1 (BRCA1). The bound complex is important in the normal double-strand break repair function of breast cancer, type 1 (BRCA1). This gene may be a target of germline cancer-inducing mutations. This protein also appears to be important in ovarian cancer where it seems to act as a tumor suppressor. Mutations in BRIP1 are associated with a 10-15% risk of ovarian cancer. BRIP1 appears to have an important role in neuronal cells by suppressing oxidative stress, excitotoxicity induced DNA damage, and in protecting the integrity of mitochondria. A deficiency of BRIP1 causes increased DNA damage, mitochondrial abnormalities and neuronal cell death. DNA repair BRIP1 protein is a DNA helicase that is employed in homologous recombinational repair, and in the response of the cell to DNA replication stress. In part, BRIP1 carries out its function through interaction with other key DNA repair proteins, specifically MLH1, BRCA1 and BLM. This group of proteins helps to ensuring genome stability, and in particular repairs DNA double-strand breaks during prophase 1 of meiosis. Interactions BRIP1 has been shown to interact with BRCA1.

https://en.wikipedia.org/wiki/CARD11
Caspase recruitment domain-containing protein 11 also known as CARD-containing MAGUK protein 1 (Carma 1) is a protein in the CARD-CC protein family that in humans is encoded by the CARD11 gene. CARD 11 is a membrane associated protein that is found in various human tissues, including the thymus, spleen, liver, and peripheral blood leukocytes. Similarly, CARD 11 is also found in abundance in various lines of cancer cells. Function The protein encoded by this gene belongs to the membrane-associated guanylate kinase (MAGUK) family, a class of proteins that functions as molecular scaffolds for the assembly of multiprotein complexes at specialized regions of the plasma membrane. This protein is also a member of the CARD protein family, which is defined by carrying a characteristic caspase-associated recruitment domain (CARD). CARD11 (CARMA1) has a domain structure similar to that of CARD10 (CARMA3) and CARD14 (CARMA2) as a member of the CARD-CC family with a C terminal MAGUK domain (the so-called CARMA proteins). The CARD domain of proteins in the CARD-CC family have been shown to specifically interact with BCL10, a protein known to function as a positive regulator of NF-κB activation by recruitment and activation of MALT1. When overexpressed in cells, this protein family activates NF-κB and induces the phosphorylation of BCL10. CARD11 is critical for T cell and B cell function and is activated after T cell receptor or B cell receptor stimulation. After receptor stimulation, C
https://en.wikipedia.org/wiki/MAP1LC3A
Microtubule-associated proteins 1A/1B light chain 3A is a protein that in humans is encoded by the MAP1LC3A gene. Two transcript variants encoding different isoforms have been found for this gene. Function MAP1A and MAP1B are microtubule-associated proteins which mediate the physical interactions between microtubules and components of the cytoskeleton. MAP1A and MAP1B each consist of a heavy chain subunit and multiple light chain subunits. The protein encoded by this gene is one of the light chain subunits and can associate with either MAP1A or MAP1B. MAPLC3A is one of the mammalian homologues of yeast ATG8, an important marker and effector of autophagy. Regulation MAP1LC3A is regulated by several post-translational modifications. These include covalent linkage of the C-terminus to phosphatidylethanolamine in autophagic membranes, and phosphorylation by protein kinase A, which downregulates its autophagy functions. Noncovalent interactions are important for its cargo targeting functions in selective autophagy. For example, it has been shown to interact with sequestosome 1. References Further reading
https://en.wikipedia.org/wiki/MotherRock
MotherRock was an energy sector hedge fund, one of the biggest traders of natural gas derivatives in New York, with assets of around $430 million at one point. It closed in August 2006 due losing money on its bets that natural gas prices would fall. In 2006 the summer heat led to prices increasing and in June 2006 MotherRock Energy Fund lost 24.6 percent and then in July 25.5 percent. Leveraged positions exacerbated the situation and eventually led to a loss of around $230 million in June and July 2006. History The fund was started by J. Robert Collins, with Conrad Goerl and ex-NYMEX vice president John D'Agostino in early 2005. Senate findings When investigating sudden price movements in the natural gas markets, and specifically the role Amaranth Advisors played in these movements, it was ascertained that Amaranth's aggressive trading was the only reason for MotherRock's collapse. It was found that Amaranth could distort market prices through large trades. On July 31, 2006, Amaranth's trading caused a 72% jump in the price spread that directly affected MotherRock's positions so badly that the latter could not meet its margin calls. MotherRock folded soon afterwards.

https://en.wikipedia.org/wiki/Body%20schema
Body schema is a concept used in several disciplines, including psychology, neuroscience, philosophy, sports medicine, and robotics. The neurologist Sir Henry Head originally defined it as a postural model of the body that actively organizes and modifies 'the impressions produced by incoming sensory impulses in such a way that the final sensation of body position, or of locality, rises into consciousness charged with a relation to something that has happened before'. As a postural model that keeps track of limb position, it plays an important role in control of action. It involves aspects of both central (brain processes) and peripheral (sensory, proprioceptive) systems. Thus, a body schema can be considered the collection of processes that registers the posture of one's body parts in space. The schema is updated during body movement. This is typically a non-conscious process, and is used primarily for spatial organization of action. It is therefore a pragmatic representation of the body’s spatial properties, which includes the length of limbs and limb segments, their arrangement, the configuration of the segments in space, and the shape of the body surface. Body schema also plays an important role in the integration and use of tools by humans. A clear differentiation of body schema from body image has developed gradually.

https://en.wikipedia.org/wiki/Medial%20giant%20interneuron
The medial giant interneuron (MG) is an interneuron in the abdominal nerve cord of crayfish. It is part of the system that controls the caridoid escape reaction of crayfish, clawed lobsters, and other decapod crustaceans. Crayfish have a pair of medial giants running the length of the entire animal, and are the largest neurons in the animal. When a crayfish is given a sudden visual or tactile stimulus to the front part of the animal, the MG activates fast flexor motor neurons that cause the abdomen to flex, resulting in the crayfish moving directly backward, away from the source of the stimulation. This connection was first demonstrated by C. A. G. Wiersma in the red swamp crayfish, Procambarus clarkii. The medial giant interneurons are less well studied than the lateral giant neurons, which trigger a similar escape behavior. See also Squid giant axon References Neurons Crayfish

Plane Dumb is the 12th Van Beuren Tom and Jerry cartoon, released on June 4, 1932. The cartoon's soundtrack is done by Gene Rodemich. Plot Tom and Jerry are flying a small airplane and find themselves off the coast of Africa. In an ill-advised effort to fit in among the natives, the two decide to don blackface and talk in a stereotypical African-American dialect. While doing this, the plane goes off balance and crashes into the ocean. After encounters with sharks, an overly-friendly octopus, and a whale, Tom and Jerry make it to the mainland. They are confronted by beasts of the African jungle, from which they take refuge in a cave, where they meet some skeletal Africans that were retooled from the first Tom and Jerry short, "Wot a Night." Once Tom and Jerry come out of the cave, African tribesmen (also stereotypically portrayed as spear-chuckers with bones in their hair) appear from behind almost every rock and crevice, outraged at the sight of the two in blackface, and begin an angry pursuit. The cartoon ends with Tom and Jerry wiping the blackface off their face, still running away from the Africans.
