Anti-PSMD5 antibodies are used in the immunodetection of the protein proteasome 26S subunit, non-ATPase 5. In humans, the canonical protein has a reported length of 504 amino acid residues and a mass of 56.2 kDa. Up to 2 different isoforms have been reported for this protein. A member of the Proteasome subunit S5B/HSM3 protein family, PSMD5 is known to act as a chaperone during the assembly of the 26S proteasome, specifically of the base subcomplex of the PA700/19S regulatory complex (RC). Synonyms for this target antigen include 26S proteasome non-ATPase regulatory subunit 5, 26S protease subunit S5 basic, 26S proteasome subunit S5B, proteasome (prosome, macropain) 26S subunit, non-ATPase, 5, and S5B. PSMD5 gene orthologs have been reported in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species. Some PSMD5 antibodies may have been used in research and have associated citations. These antibodies are most commonly used in Western Blot experiments, among other applications.
