Predicted to enable protein C-terminus binding activity and protein homodimerization activity. Predicted to be involved in several processes, including proteolysis involved in cellular protein catabolic process; regulation of cell cycle process; and regulation of exosomal secretion. Predicted to act upstream of or within several processes, including cholesterol transport; endosome organization; and potassium ion transport. Predicted to be located in several cellular components, including Flemming body; endosome membrane; and microtubule cytoskeleton. Orthologous to human VPS4B (vacuolar protein sorting 4 homolog B).
