Component of the ESCRT-III complex, which is required for multivesicular bodies (MVBs) formation and sorting of endosomal cargo proteins into MVBs. The ESCRT-III complex is probably involved in the concentration of MVB cargo (By similarity). Component of the endosomal sorting required for transport complex III (ESCRT-III), composed at least of VPS2, VPS20, VPS24 and VPS32 (By similarity). Interacts with SKD1 (PubMed:20663085). Belongs to the SNF7 family.
