Anti-MASTL antibodies are used in the immunodetection of the protein microtubule associated serine/threonine kinase like. In humans, the canonical protein has a reported length of 879 amino acid residues and a mass of 97.3 kDa. Its subcellular localization is in the nucleus and cytoplasm. Up to 3 different isoforms have been reported for this protein. It is notably expressed in many tissues, such as the colon and tonsil. A member of the AGC Ser/Thr protein kinase protein family, MASTL is reported to be a serine/threonine kinase that plays a key role in M phase by acting as a regulator of mitosis entry and maintenance. Post-translational modifications have been described, including phosphorylation. Synonyms for this target antigen include greatwall kinase homolog, greatwall protein kinase, and serine/threonine-protein kinase greatwall. MASTL gene orthologs have been reported in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species. A number of MASTL 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.
