UGT1A1, or UDP-glucuronosyltransferase 1A1, is an enzyme that belongs to the UGT family. These enzymes play a crucial role in the process of glucuronidation, a biochemical pathway that facilitates the detoxification and elimination of endogenous and exogenous compounds. UGT1A1 is primarily responsible for the glucuronidation of bilirubin, a byproduct of hemoglobin breakdown, as well as various drugs and xenobiotics.
