Vps4 is a AAA+ family protein involved in the disassembly of ESCRT-III polymers during membrane fission events such as occur during HIV budding. Here the authors propose a structure-based model of how the conformational flexibility of Vps4 can be translated into mechanical forces to disassemble ESCRT-III during membrane fission.
