• VPS4A-VPS4B
• VPS4A/B complex
• Vta1-Vps4 complex

Definition

An ESCRT complex that has AAA-ATPase activity and is involved in ESCRT-mediated intralumenal vesicle formation and the final stages of cytokinesis. The 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. In yeast, it is formed by the AAA ATPase Vps4 and its cofactor Vta1. (6)
