Anti-PPP2R5B antibodies are used in the immunodetection of the protein protein phosphatase 2 regulatory subunit B'beta. In humans, the canonical protein has a reported length of 497 amino acid residues and a mass of 57.4 kDa. Its subcellular localization is in the cytoplasm. Up to 2 different isoforms have been reported for this protein. It is reported to be highly expressed in the brain. A member of the Phosphatase 2A regulatory subunit B56 protein family, PPP2R5B is known to be involved with neuronal development and the regulation of transcription. Post-translational modifications have been described, including ubiquitination. Synonyms for this target antigen include B56beta, PR61B, serine/threonine-protein phosphatase 2A 56 kDa regulatory subunit beta isoform, and B56B. PPP2R5B gene orthologs have been reported in the mouse, rat, bovine, frog, zebrafish and chimpanzee species. Some PPP2R5B antibodies may have been used in research and have associated citations. Western Blot is a widely used application for these antibodies. In addition, ELISA is also a common application.
