Probable microtubule-associated force-producing protein that is targeted to the forming cell plate during cytokinesis. May play a role in cell division. Localizes in the forming cell plate during cytokinesis. Expressed in root and leaf meristems. Expression is cell-cycle regulated. Expressed during mitosis from the prophase to the telophase. No visible phenotype under normal growth conditions, but when grown at 16 degrees Celsius, seedlings grow slowly and root tip cells form incomplete or twisted cell plates. Belongs to the TRAFAC class dynamin-like GTPase superfamily. Dynamin/Fzo/YdjA family. Sequencing errors.
