Anti-PPP1R12A antibodies are used in the immunodetection of the protein protein phosphatase 1 regulatory subunit 12A. In humans, the canonical protein has a reported length of 1030 amino acid residues and a mass of 115.3 kDa. Its subcellular localization is in the cytoplasm. Up to 5 different isoforms have been reported for this protein. It is reported to be expressed in striated muscles, specifically in type 2a fibers. PPP1R12A is a reported key regulator of protein phosphatase 1C (PPP1C). Post-translational modifications have been described, including phosphorylation. Synonyms for this target antigen include M130, MYPT1, myosin binding subunit, myosin phosphatase, target subunit 1, and GUBS. PPP1R12A gene orthologs have been reported in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species. Over 430 citations in the literature describe the use of PPP1R12A antibodies in research. Western Blot is a widely used application for these antibodies. ELISA, Immunofluorescence, and Immunohistochemistry are also common applications.
