Responsible for microtubule translocation. May be important for the organization of phragmoplast-specific arrays of microtubules (PubMed:7983184). Plays an essential role in stabilizing the mitotic spindle. Required during mitotic cytokinesis (By similarity). Microtubule-associated. Expressed during S phase. Expression increases as cell moves from S phase to M phase and then decreases rapidly as cell enters the G1 phase. Expression increases again during the G2 phase. Belongs to the TRAFAC class myosin-kinesin ATPase superfamily. Kinesin family. KIN-5/BimC subfamily.
