Predicted to enable ATP binding activity; microtubule binding activity; and microtubule motor activity. Acts upstream of or within cytoskeleton-dependent cytokinesis; embryonic cleavage; and vesicle transport along microtubule. Located in several cellular components, including cleavage furrow; microtubule; and nucleus. Is expressed in proliferative region. Human ortholog(s) of this gene implicated in congenital dyserythropoietic anemia type III. Orthologous to human KIF23 (kinesin family member 23).
