Vacuolar protein sorting-associated protein IST1

UniProtKB accession:  P53843

Grouped By:  Matching UniProtKB accession

UniProtKB description:  Involved in a late step in sorting of cargo proteins of the multivesicular body (MVB) for incorporation into intralumenal vesicles. The lumenal sequestrated membrane proteins are targeted into the vacuole after fusion of the endosome with the vacuole. Regulates the recruitment of VPS4 to the ESCRT-III complex, probably in conjunction with DID2, and VPS4 catalyzes the disassembly of the ESCRT-III complex.
