KIF4B

Chromosome-associated kinesin KIF4B

1234 amino acids

Motor protein that translocates PRC1 to the plus ends of interdigitating spindle microtubules during the metaphase to anaphase transition, an essential step for the formation of an organized central spindle midzone and midbody and for successful cytokinesis. May play a role in mitotic chromosomal positioning and bipolar spindle stabilization (By similarity).

Belongs to the TRAFAC class myosin-kinesin ATPase superfamily. Kinesin family. Chromokinesin subfamily.
