Structural and functional analysis indicate that this C-terminal domain promotes the ATP-dependent double ring assembly of Vps4. Furthermore, it has been shown that it is necessary and sufficient for protein dimerization. Mutations in Lys-299 and Lys-302 completely abolished the ability of Vta1 to stimulate the ATPase activity of Vps4 while mutation in Lys-322 had no effect [1].
Domain
A [auth C]PF09336Vps4 C terminal oligomerisation domain (Vps4_C)Vps4 C terminal oligomerisation domainThis domain is found at the C terminal of ATPase proteins involved in vacuolar sorting. It forms an alpha helix structure and is required for oligomerisation [1]. Domain
A [auth C]PF17862AAA+ lid domain (AAA_lid_3)AAA+ lid domainThis entry represents the alpha helical AAA+ lid domain that is found to the C-terminus of AAA domains. Domain
