Protein Information (annotations from UniProt)

Database IDHIV0007835
UniProt IDQ86VN1
Primary gene name(s)VPS36
Synonym gene name(s)C13orf9, EAP45
Protein nameVacuolar protein-sorting-associated protein 36
Protein functionComponent of the ESCRT-II complex, endosomal sorting complex required for transport II, which is required for multivesicular body, MVB formation and sorting of endosomal cargo proteins into MVBs. The MVB pathway mediates delivery of transmembrane proteins into the lumen of the lysosome for degradation. The ESCRT-II complex is probably involved in the recruitment of the ESCRT-III complex. Its ability to bind ubiquitin probably plays a role in endosomal sorting of ubiquitinated cargo proteins by ESCRT complexes. The ESCRT-II complex may also play a role in transcription regulation, possibly via its interaction with ELL. Binds phosphoinosides such as PtdIns(3,4,5P3.
Subcellular locationCytoplasm. Endosome. Late endosome {ECO:0000250|UniProtKB:Q91XD6}. Membrane. Nucleus {ECO:0000305}. Note=Colocalizes with ubiquitinated proteins on late endosomes. Recruited to the endosome membrane to participate in vesicle formation. {ECO:0000250|UniProtKB:Q91XD6}.
