Anti-PPM1A antibodies are used in the immunodetection of the protein protein phosphatase, Mg2+/Mn2+ dependent 1A. In humans, the canonical protein has a reported length of 382 amino acid residues and a mass of 42.4 kDa. Its subcellular localization is in the nucleus and cytoplasm. Up to 3 different isoforms have been reported for this protein. It is notably widely expressed in many tissue types. A member of the PP2C protein family, PPM1A is known to be involved with the regulation of transcription. Post-translational modifications have been described, including myristoylation and phosphorylation. Synonyms for this target antigen include PP2CA, PP2Calpha, protein phosphatase 1A, and PP2C-ALPHA. PPM1A gene orthologs have been reported in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species. Over 100 citations in the literature describe the use of PPM1A antibodies in research. Western Blot is a widely used application for these antibodies. ELISA, Immunocytochemistry, Immunofluorescence, and Immunohistochemistry are also common applications.
