Anti-CAVIN2 antibodies are used in the immunodetection of the protein caveolae associated protein 2. In humans, the canonical protein has a reported length of 425 amino acid residues and a mass of 47.2 kDa. Its subcellular localization is in the cytoplasm. It is reported to be highly expressed in the heart and lung, and expressed at lower levels in the brain, kidney, liver, pancreas, placenta, and skeletal muscle. A member of the CAVIN protein family, CAVIN2 is known to play an important role in caveolar biogenesis and morphology. Post-translational modifications have been described, including phosphorylation. Synonyms for this target antigen include SDPR, SDR, phosphatidylserine-binding protein, serum deprivation response, serum deprivation-response protein, and PS-p68. CAVIN2 gene orthologs have been reported in the mouse, rat, bovine, frog, chimpanzee and chicken species.
