Kif2a (Kinesin-like protein KIF2A or Kinesin-2) belongs to Kinesin-13 family that includes Kif2a, Kif2b and Kif2c members which are classified as microtubule depolymerases with potential of depolymerizing microtubules at their ends. Among these proteins, Kif2a specifically localizes to centrosomes during mitotic cell division and is essential to normal congress of chromosomes at the metaphase plate, normal spindle dynamics/turnover and for the formation of bipolar mitotic spindles. Kif2a gets localized to the spindle microtubules and spindle poles from prophase to metaphase. Kif2a-PSRC1 interactions leads to its recruitment to mitotic spindles, PLK1 kiase activity is required for Kif2a targeting to spindle microtubules and spindle poles. siRNA knockdown of Kif2a in human cancer cells or Kif2a blocking with antibody addition to Xenopus eggs leads to monopolar spindles formation and cell cycle block suggesting that Kif2a is essential for bipolar spindle assembly and normal progression of mitosis. Kif2a has been shown to be essential for proper neuronal outgrowth and its depletion caused neuronal migratory delay by changing microtubule dynamics around the cell body suggesting that Kif2a is implicated in non-mitotic cells also. Moreover, Kif2a has been established as a plus end-directed microtubule-dependent motor essential for normal brain development and that it regulates microtubule dynamics during axonal growth.

FAQs for Kif2a Antibody (NB500-180). (Showing 1 - 2 of 2 FAQs).

  1. Can you provide the immunogen sequence for the Kif2a Antibody Cat. No. NB500-180? If considered proprietary, can you provide the % homology with drosophila?
    • The exact immunogen sequence of NB500-180 is proprietary, but it falls within amino acids 1-120 of human Kif2A (Accession #: O00139). Based on an alignment of the immunogen with the Drosophila melanogaster sequence, I am getting a homology of about 25%.
  2. We receive an enquiry about the following antibody: Anti-Kif2a antibody (NB 500-180). The customer would like to know the immunogen of the antibody. If this information is not available, I would appreciate if you could at least give the amino acids range at the N-ter recognized by the antibody.
    • Unfortunately many of our immunogen sequences are proprietary and we are unable to disclose the exact amino acid range. However, we can confirm you that the immunogen which was used to generate our Kif2a antibody with catalogue number NB500-180 is derived from a region within the first 150 amino acids of the protein.
