Anti-katanin interacting protein antibodies are used for the immunodetection of the protein encoded by the KATNIP gene. In humans, the canonical protein has a reported length of 1618 amino acid residues and a mass of 180.9 kDa. Its subcellular localization is in the cytoplasm. It is believed to influence the stability of microtubules (MT), possibly through interaction with the MT-severing katanin complex. The gene encoding this protein is implicated in Joubert syndrome. Other names for this target antigen include JBTS26 and KIAA0556. Gene orthologs have been identified in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species.
