======= MVB12B ======= == Gene Information == * **Official Symbol**: MVB12B * **Official Name**: multivesicular body subunit 12B * **Aliases and Previous Symbols**: N/A * **Entrez ID**: [[https://www.ncbi.nlm.nih.gov/gene/?term=89853|89853]] * **UniProt**: [[https://www.uniprot.org/uniprot/Q9H7P6|Q9H7P6]] * **Interactions**: [[https://thebiogrid.org/search.php?search=MVB12B&organism=9606|BioGRID]] * **PubMed articles**: [[https://www.ncbi.nlm.nih.gov/pubmed/?term=gene%20MVB12B|Open PubMed]] * **OMIM**: N/A == Function Summary == * **Entrez Summary**: The protein encoded by this gene is a component of the ESCRT-I complex, a heterotetramer, which mediates the sorting of ubiquitinated cargo protein from the plasma membrane to the endosomal vesicle. ESCRT-I complex plays an essential role in HIV budding and endosomal protein sorting. Depletion and overexpression of this and related protein (MVB12A) inhibit HIV-1 infectivity and induce unusual viral assembly defects, indicating a role for MVB12 subunits in regulating ESCRT-mediated virus budding. Alternatively spliced transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Aug 2011]. * **UniProt Summary**: Component of the ESCRT-I complex, a regulator of vesicular trafficking process. Required for the sorting of endocytic ubiquitinated cargos into multivesicular bodies. |DUF2464| |virus maturation| |ESCRT I complex| |ubiquitin-dependent protein catabolic process via the multivesicular body sorting pathway| |viral budding| |virion assembly| |intracellular transport of virus| |host cell| |transport of virus| |multi-organism localization| |multi-organism transport| |ubiquitin binding| |regulation of epidermal growth factor receptor signaling pathway| |regulation of ERBB signaling pathway| |late endosome membrane| |late endosome| |vesicle| |lipid binding| |viral life cycle| |endosome membrane| |endosomal transport| |early endosome| |ubiquitin-dependent protein catabolic process| |modification-dependent protein catabolic process| |modification-dependent macromolecule catabolic process| |proteolysis involved in cellular protein catabolic process| |cellular protein catabolic process| |protein catabolic process| |viral process| |symbiotic process| |interspecies interaction between organisms| |cellular macromolecule catabolic process| |macromolecule catabolic process| |organonitrogen compound catabolic process| |proteolysis| |protein transport| |intracellular transport| |peptide transport| |amide transport| |establishment of protein localization| |organic substance catabolic process| |cellular catabolic process| |establishment of localization in cell| |nitrogen compound transport| |vesicle-mediated transport| \\ === CRISPR Data === ^Screen^Score^ |[[:results:exp517|Quercetin 20μM R08 exp517]]|-2.04| |[[:results:exp237|NN-Diethyl-meta-toluamide 100μM R05 exp237]]|-1.92| |[[:results:exp453|B02 10μM R08 exp453]]|-1.76| |[[:results:exp435|JQ1 0.8μM R08 exp435]]|-1.73| No correlation found to any other genes in chemogenomics.
