Anti-PSMB7 antibodies are used in the immunodetection of the protein proteasome 20S subunit beta 7. In humans, the canonical protein has a reported length of 277 amino acid residues and a mass of 30 kDa. Its subcellular localization is in the nucleus and cytoplasm. Up to 2 different isoforms have been reported for this protein. It is noted to be expressed at a low level in colonic mucosa. A member of the Peptidase T1B protein family, PSMB7 is a known component of the 20S core proteasome complex involved in the proteolytic degradation of most intracellular proteins. Synonyms for this target antigen include epididymis secretory sperm binding protein, macropain chain Z, multicatalytic endopeptidase complex chain Z, proteasome (prosome, macropain) subunit, beta type, 7, and proteasome subunit beta type-7. PSMB7 gene orthologs have been reported in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species. A number of PSMB7 antibodies have been mentioned in research publications and have associated citations. Western Blot is a widely used application for these antibodies. In addition, Immunohistochemistry is also a common application.
