Anti-PPP3R2 antibodies are used in the immunodetection of the protein protein phosphatase 3 regulatory subunit B, beta. In humans, the canonical protein has a reported length of 170 amino acid residues and a mass of 19.5 kDa. Its subcellular localization is in the mitochondria. It is reported to have testis-specific expression. A member of the Calcineurin regulatory subunit protein family, PPP3R2 is a regulatory subunit of calcineurin, a calcium-dependent, calmodulin stimulated protein phosphatase. Synonyms for this target antigen include calcineurin subunit B type 2, CBLP, CNBII, calcineurin B, type II (19kDa), calcineurin B-like protein, and PPP3RL. PPP3R2 gene orthologs have been reported in the mouse, rat, bovine and chimpanzee species. A number of PPP3R2 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.
