Anti-ARPG836 antibodies enable researchers to detect and measure the ARPG836 antigen in biological samples. This target is a reported synonym of the DHRS11 gene, which encodes dehydrogenase/reductase 11. This protein is known to catalyze the conversion of the 17-keto group of estrone, 4- and 5-androstenes and 5-alpha-androstanes into their 17-beta-hydroxyl metabolites and the conversion of the 3-keto group of 3-, 3,17- and 3,20- diketosteroids into their 3-hydroxyl metabolites. The human version of ARPG836 has a canonical amino acid length of 260 residues and a protein mass of 28.3 kilodaltons, although 3 isoforms have been identified. It is reported to be a secreted protein that is notably expressed in the rectum, kidney, duodenum, colon, and appendix. ARPG836 is a member of the Short-chain dehydrogenases/reductases (SDR) protein family.
