Protein Information (annotations from UniProt)

Database IDHIV0004261
UniProt IDQ8WUX9
Primary gene name(s)CHMP7
Synonym gene name(s)unknown
Protein nameCharged multivesicular body protein 7
Protein functionESCRT-III-like protein required to recruit the ESCRT-III complex to the nuclear envelope during late anaphase, PubMed:26040712. Together with SPAST, the ESCRT-III complex promotes nuclear envelope sealing and mitotic spindle disassembly during late anaphase, PubMed:26040712. Plays a role in the endosomal sorting pathway, PubMed:16856878. {ECO:0000269|PubMed:16856878, ECO:0000269|PubMed:26040712}.
Subcellular locationCytoplasm {ECO:0000269|PubMed:16856878}. Nucleus envelope {ECO:0000269|PubMed:26040712}. Note=Diffused localization, with some punctate distribution, especially in the perinuclear area, PubMed:16856878. Localizes to the nucleus envelope during late anaphase, PubMed:26040712. {ECO:0000269|PubMed:16856878, ECO:0000269|PubMed:26040712}.
