Involved in cytokinesis. May hydrolyze GTP. GTP + H2O = GDP + H(+) + phosphate During cytokinesis, found in the cleavage furrow. Expression begins during cell cycle progression, between 12 and 24 hours after germination. Reach a maximum around mid-log phase and disappear during the stationary phase. Expressed in the central funnel of cells of migrating slugs and at the top of rising culminants. Not expressed until the slug stage. Induced by STATa. Produced cells are larger and a large amount of them contains more than 2 nuclei. Belongs to the TRAFAC class dynamin-like GTPase superfamily. Dynamin/Fzo/YdjA family.
