Protein Information (annotations from UniProt)

Database IDHIV0001565
UniProt IDO95239
Primary gene name(s)KIF4A
Synonym gene name(s)KIF4
Protein nameChromosome-associated kinesin KIF4A
Protein functionMotor 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. {ECO:0000269|PubMed:15297875, ECO:0000269|PubMed:15625105}.
Subcellular locationNucleus matrix. Cytoplasm, cytoskeleton, spindle. Midbody. Chromosome. Note=Not present in the nucleolus. In early mitosis, associated with the mitotic spindle, in anaphase, localized to the spindle midzone and, in telophase and cytokinesis, to the midbody. In late cytokinesis, found in the center of the midbody. Associated with chromosomes at all stages of mitosis.
