The human RCA locus is located on chromosome 1 (CA1) and consists of approximately 750 kb.
CR1 (CD35) and CR2 (CD21) are structurally related integral transmembrane glycoproteins that function as cellular receptors for human C3b and C3dg, respectively. The primary sequence of the most common structural allotype of CR1 and that of CR2 have been established, and ligand binding on the molecules has been map...
Is there a role for TET proteins in invariant natural killer T cells (iNKT) cell fate?
Yes. Tet2-TET proteins regulate the lineage specification and TCR-mediated expansion of iNKT cells. TETs are ubiquitously expressed and play diverse roles in gene regulation, imprinting, insulation, intra/interchromosomal interactions, nuclear compartmentalisation, and alternative splicing. Depletion of Tet2 and its li...
TET proteins oxidize 5-methylcytosine in DNA to 5-hydroxymethylcytosine and other oxidation products. We found that simultaneous deletion of Tet2 and Tet3 in mouse CD4+CD8+ double-positive thymocytes resulted in dysregulated development and proliferation of invariant natural killer T cells (iNKT cells). Tet2-Tet3 d...

STUDY DESIGN: A fixed-effects reliability s...
What is the function of the PDZ domain in SATB1?
N-terminal PDZ-like domain of chromatin organizer SATB1 contributes towards its function as transcription regulator. We found this dimerization region to have sequence similarity to PDZ domains, which have been previously shown to be involved in signaling by conferring protein-protein interactions. These studies clearl...
SATB1 is expressed primarily in thymocytes and orchestrates temporal and spatial expression of a large number of genes in the T-cell lineage. SATB1 binds to the bases of chromatin loop domains in vivo, recognizing a special DNA context with strong base-unpairing propensity. The majority of thymocytes are eliminated ...
What cellular process is the protein clathrin involved in?
Clathrin is a central regulator of endocytosis in all eukaryotes that plays a role in bacterial and plastid differentiation
Receptor-mediated endocytosis proceeds by transfer of receptor-ligand complexes from clathrin-coated pits at the cell surface to uncoated endocytic vesicles termed receptosomes (or endosomes). These vesicles have now been purified more than 37-fold based on their content of newly internalized epidermal growth facto...

No, Thymoquinone has been found to be effective against radiation induced enteritis
Radiation enteritis is an old but emerging question induced by the application of radiation. However, no effective drugs for radiation enteritis in clinic. In this study, we found that thymoquinone (TQ) could mitigate intestinal damages induced by irradiation. After exposure to irradiation, TQ-treated improved the ...
Which are the databases for intrinsic protein disorders?
Intrinsic disorder (ID), i.e. the lack of a unique folded conformation at physiological conditions, is a common feature for many proteins, which requires specialized biochemical experiments that are not high-throughput. DisProt and MobiDB are databases for intrinsic protein disorders.
BACKGROUND: Intrinsic protein disorder is becoming an increasingly important topic in protein science. During the last few years, intrinsically disordered proteins (IDPs) have been shown to play a role in many important biological processes, e.g. protein signalling and regulation. This has sparked a need to better ...
List the 5 different human immunoglobulin heavy chains.
The 5 human immunoglobulin heavy chains are Alpha, Delta Epsilon, Gamma and Mu
In mature B cells of mice and most mammals, cellular release of single H chain Abs without L chains is prevented by H chain association with Ig-specific chaperons in the endoplasmic reticulum. In precursor B cells, however, surface expression of mu-H chain in the absence of surrogate and conventional L chain has be...
Has the Spanich flu virus been reconstructed?
Tes, Reconstruction of the 1918 influenza virus has facilitated considerable advancements in our understanding of this extraordinary pandemic virus.
The influenza pandemic of 1918-1919 killed approximately 50 million people. The unusually severe morbidity and mortality associated with the pandemic spurred physicians and scientists to isolate the etiologic agent, but the virus was not isolated in 1918. In 1996, it became possible to recover and sequence highly d...

Siponimod is a functional sphingosine-1-phosphate (S1P) antagonist.
BACKGROUND: Siponimod is an oral selective modulator of sphingosine 1-phosphate receptor types 1 and type 5, with an elimination half-life leading to washout in 7 days. We aimed to determine the dose-response relation of siponimod in terms of its effects on brain MRI lesion activity and characterise safety and tole...
What is a zoonotic virus?
A zoonotic disease is a disease that can be passed from animals to humans. Zoonotic viruses may adapt to a human host eventually becoming endemic in humans, but before doing so punctuated outbreaks of the zoonotic virus may be observed.
Monkeypox virus (MPXV), a close relative of Variola virus, is a zoonotic virus with an unknown reservoir. Interaction with infected wildlife, bites from peri-domestic animals, and bushmeat hunting are hypothesized routes of infection from wildlife to humans. Using a Risk Questionnaire, performed in monkeypox-affect...

What is the function of BRD4?
As a member of the bromodomain and extraterminal (BET) family, BRD4 (bromodomain containing 4) can bind to acetylated histones and transcription factors, and is also able to recruit various transcriptional regulators. As transcriptional coactivator, BRD4 represses autophagy and lysosomal function.
The papillomavirus E2 protein is a critical viral regulatory protein with transcription, DNA replication, and genome maintece functions. We have previously identified the cellular bromodomain protein Brd4 as a major E2-interacting protein and established that it participates in tethering bovine papillomavirus type ...

Is SATB1 necessary for T-cell maturation?
Special AT-rich sequence binding protein 1 (SATB1) regulates gene expression essential in immune T-cell maturation and switching of fetal globin species, by binding to matrix attachment regions (MARs) of DNA and inducing a local chromatin remodeling.
Special AT-rich binding protein 1 (SATB1) nuclear protein, expressed predomitly in T cells, regulates genes through targeting chromatin remodeling during T-cell maturation. Here we show SATB1 family protein induction during early human adult erythroid progenitor cell differentiation concomitant with epsilon-globin ...
For how long do Drosophila embryos use maternal genome mRNA?
mitoses before interphase 14 run on maternal products and occur in metasynchronous waves
In Drosophila embryogenesis, mitotic control undergoes a significant transition during the 14th interphase. Mitoses before interphase 14 run on maternal products, and occur in metasynchronous waves. Mitoses after interphase 14 require zygotic transcription, and occur asyncronously in an intricate, highly ordered sp...
