FunctionVPS4_YEAST Involved in the transport of biosynthetic membrane proteins from the prevacuolar/endosomal compartment to the vacuole. Required for multivesicular body (MVB) protein sorting. Catalyzes the ATP-dependent dissociation of class E VPS proteins from endosomal membranes, such as the disassembly of the ESCRT-III complex.[1] [2] [3] Publication Abstract from PubMedThe ESCRT pathway's AAA+ ATPase, Vps4p, remodels ESCRT-III complexes to drive membrane fission. Here, we use peptide binding assays to further the understanding of substrate specificity and the mechanism of autoinhibition. Our results reveal unexpected sequence preference to the substrate binding groove and an elegant mechanism of regulation that couples localization to substrate with release from autoinhibition.
