Abstract

Background: Vta1 promotes Vps4 ATPase activity and facilitates ESCRT-III stimulation of Vps4. Results: The Vta1 VSE (Vps4 stimulatory element) mediates ESCRT-III-enhanced activation of Vps4 and contributes to Vta1 function in vivo. Conclusion: ESCRT-III binding Vta1 relieves autoinhibition of the VSE to promote activation of Vps4. Significance: These studies identify a novel mechanism whereby ESCRT-III and Vta1 regulate Vps4 activity.
