Microtubule-associated force-producing protein involved in producing microtubule bundles and able to bind and hydrolyze GTP. Most probably involved in vesicular trafficking processes. Involved in receptor-mediated endocytosis (By similarity). GTP + H2O = GDP + H(+) + phosphate Interacts with CAV1 and SH3GLB1. Binds SH3GL1, SH3GL2 and SH3GL3. Interacts with SNX9. Interacts with SNX33 (via SH3 domain). Interacts with MYO1E (via SH3 domain). Interacts with PHOCN. Interacts with PACSIN1, PACSIN2 and PACSIN3. Interacts with UNC119; leading to a decrease of DNM1 GTPase activity. Interacts with DIAPH1. Interacts with AMPH, BIN1 AND SYNJ1 (By similarity). Microtubule-associated. Belongs to the TRAFAC class dynamin-like GTPase superfamily. Dynamin/Fzo/YdjA family.
