Background	Vacuolar protein sorting-associated protein 4B (VPS4B) is a member of the AAA (ATPases associated with diverse cellular activities) family. VPS4B is involved in late steps of the endosomal multivesicular bodies (MVB) pathway and recognizes membrane-associated ESCRT-III assemblies and catalyzes their disassembly, probably in combination with membrane fission. A dominant negative mutant of VPS4B inhibits vacuolar protein sorting and also arrest HIV-1 and MLV budding.
Description	VPS4B Human Recombinant expressed in E.Coli is a single, non-glycosylated polypeptide chain containing 468a.a. (1-444 a.a) and having a molecular weight of 51.8kDa. VPS4B is fused to a 24a.a. His-tag at N-terminus and purified by unique purification methods.
