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. The Vps4-Vta1 complex catalyzes disassembly of the ESCRT-III filament around the neck of the budding vesicle in an ATP-driven reaction, resulting in membrane scission and recycling of the ESCRT-III components back to the cytosol.
