Anti-CAVIN3 antibodies are used in the immunodetection of the protein caveolae associated protein 3. In humans, the canonical protein has a reported length of 261 amino acid residues and a mass of 27.7 kDa. Its subcellular localization is in the cytoplasm. It is notably expressed in the smooth muscle, skin, fallopian tube, cerebral cortex, and bronchus. A member of the CAVIN protein family, CAVIN3 is reported to regulate the traffic and/or budding of caveolae. Post-translational modifications have been described, including phosphorylation. Synonyms for this target antigen include sdr-related gene product that binds to c-kinase, serum deprivation response factor-related gene product that binds to C-kinase, and protein kinase C delta binding protein. CAVIN3 gene orthologs have been reported in the mouse, rat, bovine and chimpanzee species.
