  • Application notes
    Is unsuitable for ICC,IHC-P or IP.
  • Target

    • Function

      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.
    • Tissue specificity

      Highly expressed in hematopoietic tissues, fetal liver, spleen, thymus and adult thymus and bone marrow. Lower levels are found in heart, testis, kidney, colon and lung.
    • Sequence similarities

      Belongs to the kinesin-like protein family. Chromokinesin subfamily.
      Contains 1 kinesin-motor domain.
    • Cellular localization

      Nucleus matrix. Cytoplasm > cytoskeleton > spindle. Midbody. Chromosome. 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.
