Anti-small glutamine rich tetratricopeptide repeat co-chaperone beta antibodies are used for the immunodetection of the protein encoded by the SGTB gene. In humans, the canonical protein has a reported length of 304 amino acid residues and a mass of 33.4 kDa. A member of the SGT protein family, it is a reported co-chaperone that binds directly to HSC70 and HSP70 and regulates their ATPase activity. Other names for this target antigen include small glutamine-rich tetratricopeptide repeat-containing protein beta, beta-SGT, small glutamine rich protein with tetratricopeptide repeats 2, and SGT2. Gene orthologs have been identified in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species.
