Anti-TAO kinase 1 antibodies are used for the immunodetection of the protein encoded by the TAOK1 gene. In humans, the canonical protein has a reported length of 1001 amino acid residues and a mass of 116.1 kDa. Its subcellular localization is in the cytoplasm. Alternative splicing is reported to yield 3 different isoforms for this protein. It is reported to be highly expressed in the testis, and to a lower extent also expressed in the brain, placenta, colon and skeletal muscle. A member of the STE Ser/Thr protein kinase protein family, it is known to be a protein kinase involved in various processes such as p38/MAPK14 stress-activated MAPK cascade, DNA damage response and regulation of cytoskeleton stability. Other names for this target antigen include MARK Kinase, STE20-like kinase PSK2, kinase from chicken homolog B, microtubule affinity regulating kinase kinase, and serine/threonine-protein kinase TAO1. A number of TAO kinase 1 antibodies have been mentioned in research publications and have associated citations. Western Blot is a widely used application for these antibodies. ELISA and Immunohistochemistry are also common applications.
