Previous studies suggest that VCP predominantly exists as a homohexamer. Here, we performed structural and biochemical characterization of VCP dodecamer, an understudied state of VCP. The structure revealed an apo nucleotide status that has rarely been captured, a tail-to-tail assembly of two hexamers, and the up-elevated N-terminal domains akin to that seen in the ATP-bound hexamer. Further analyses elucidated a nucleotide status-dependent dodecamerization mechanism, where nucleotide dissociation from the D2 AAA domains induces and promotes VCP dodecamerization. In contrast, nucleotide-free D1 AAA domains are associated with the up-rotation of N-terminal domains, which may prime D1 for ATP binding. These results therefore reveal new nucleotide status-dictated intra- and interhexamer conformational changes and suggest that modulation of D2 domain nucleotide occupancy may serve as a mechanism in controlling VCP oligomeric states. | |||||||||
