Anti-CIP2A antibodies are used in the immunodetection of the protein cellular inhibitor of PP2A. In humans, the canonical protein has a reported length of 905 amino acid residues and a mass of 102.2 kDa. Its subcellular localization is in the membrane and cytoplasm. Up to 2 different isoforms have been reported for this protein. It is reported to be expressed at low levels in most of the tissues. CIP2A is a reported oncoprotein that inhibits PP2A and stabilizes MYC in human malignancies. Synonyms for this target antigen include cancerous inhibitor of PP2A, cancerous inhibitor of protein phosphatase 2A, cell proliferation regulating inhibitor of protein phosphatase 2A, p90 autoantigen, and protein CIP2A. CIP2A gene orthologs have been reported in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species. Over 80 citations in the literature describe the use of CIP2A antibodies in research. Western Blot is a widely used application for these antibodies. In addition, Immunohistochemistry is also a common application.
