Anti-kinesin family binding protein antibodies are used for the immunodetection of the protein encoded by the KIFBP gene. In humans, the canonical protein has a reported length of 621 amino acid residues and a mass of 71.8 kDa. Its subcellular localization is in the cytoplasm. It is reported to be highly expressed in the heart, brain, ovary, testis, spinal cord and all specific brain regions examined. A member of the KIF-binding protein family, it is known to be required for organization of axonal microtubules, and axonal outgrowth and maintenance during peripheral and central nervous system development. The gene encoding this protein is implicated in Goldberg-Shprintzen syndrome. Other names for this target antigen include KIAA1279, KIF1BP, TTC20, KIF-binding protein, KIF1 binding protein, and KBP. Gene orthologs have been identified in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species.
