Function

[VTA1_YEAST] Has a role in the formation of the multivesicular body (MVB). Required for the sorting of lipids to form intralumenal vesicles and for fluid-phase transport to the vacuole. Required for sorting the plasma membrane proteins STE2 and STE3 into the MVB. Acts a cofactor of VSP4, promotes the oligomerization of VPS4 and stimulates its ATPase activity by 6- to 8-fold.^[1] ^[2] ^[3] ^[4]

Publication Abstract from PubMed

The MVB pathway plays essential roles in several eukaryotic cellular processes. Proper function of the MVB pathway requires reversible membrane association of the ESCRTs, a process catalyzed by Vps4 ATPase. Vta1 regulates the Vps4 activity, but its mechanism of action was poorly understood. We report the high-resolution crystal structures of the Did2- and Vps60-binding N-terminal domain and the Vps4-binding C-terminal domain of S. cerevisiae Vta1. The C-terminal domain also mediates Vta1 dimerization and both subunits are required for its function as a Vps4 regulator. Emerging from our analysis is a mechanism of regulation by Vta1 in which the C-terminal domain stabilizes the ATP-dependent double ring assembly of Vps4. In addition, the MIT motif-containing N-terminal domain, projected by a long disordered linker, allows contact between the Vps4 disassembly machinery and the accessory ESCRT-III proteins. This provides an additional level of regulation and coordination for ESCRT-III assembly and disassembly.
