The ESCRT (Endosomal Sorting Complexes Required for Transport) machinery is made up of five complexes, ESCRT-0 to -III and the Vps4-Vta1 ATPase complex, which are sequentially recruited to the cytosolic face of the membrane, and mediate cargo recognition, membrane budding and fission. ESCRT-0 initiates mediates multivesicular body (MVB) formation, binding ubiquitinated membrane proteins destined for degradation and concentrating them in early endosome membranes. ESCRT-0 recruits ESCRT-I. (Adapted from PMID:22361144 and FBrf0209668).
