Synonyms:UDPGT 2B7, UDPGT 2B9, UDPGTh 2, UGT2B7, UGT2B9, UGTB2B9 Background:UDPGT is of major importance in the conjugation and subsequent elimination of potentially toxic xenobiotics and endogenous compounds. Its unique specificity for 3,4-catechol estrogens and estriol suggests it may play an important role in regulating the level and activity of these potent and active estrogen metabolites. Is also active with androsterone, hyodeoxycholic acid and tetrachlorocatechol(in vitro).
