Microtubule-associated force-producing protein involved in clathrin-mediated vesicle trafficking from the trans-Golgi network to the central vacuole. Able to bind and hydrolyze GTP. Binds specifically to phosphatidylinositol 3-phosphate (PtdIns3P). GTP + H2O = GDP + H(+) + phosphate Increased GTPase activity in the presence of phosphatidic acid. Binds PtdIns3P (PubMed:12207647). Interacts with SH3P3 (via SH3 domain) and (via C-terminus) with GAMMA-ADR (PubMed:12207647). May homooligomerize or heterooligomerize (PubMed:14750520). Localized in the forming cell plate during cytokinesis. The PH domain binds phospholipids. The PRD1 motif (721-728) is necessary for the interaction with SH3P3. Belongs to the TRAFAC class dynamin-like GTPase superfamily. Dynamin/Fzo/YdjA family.
