Anti-SRPRA antibodies are used in the immunodetection of the protein SRP receptor subunit alpha. In humans, the canonical protein has a reported length of 638 amino acid residues and a mass of 69.8 kDa. Its subcellular localization is in the ER. Up to 2 different isoforms have been reported for this protein. A member of the GTP-binding SRP protein family, SRPRA is a known component of the signal recognition particle (SRP) complex receptor (SR). Synonyms for this target antigen include SRPR, Sralpha, signal recognition particle receptor subunit alpha, DP-alpha, SR-alpha, and DP. SRPRA gene orthologs have been reported in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species. Some SRPRA antibodies may have been used in research and have associated citations. These antibodies are most commonly used in Western Blot experiments, among other applications.
