UGT1A1 (UDP-glucuronosyltransferase 1A1) is an enzyme. The public catalogues list it as a drug target and a biomarker, and an approved or late-stage drug is recorded against it. This dossier gathers the 0 products (0 approved), 0 trials, 0 pathways and 0 resistance routes in the corpus that involve it, with external identifiers so it can be joined to UniProt, ChEMBL, Open Targets and the rest of biology.

Biology

UDP-glucuronosyltransferase (UGT) that catalyses phase II biotransformation reactions in which lipophilic substrates are conjugated with glucuronic acid to increase the metabolite's water solubility, thereby facilitating excretion into either the urine or bile. Essential for the elimination and detoxification of drugs, xenobiotics and endogenous compounds. Catalyses the glucuronidation of endogenous oestrogen hormones such as estradiol, estrone and estriol. Involved in the glucuronidation of bilirubin, a degradation product occurring in the normal catabolic pathway that breaks down heme in vertebrates. Involved in the glucuronidation of arachidonic acid (AA) and AA-derived eicosanoids including 15-HETE, 20-HETE, PGB1 and F2-isoprostane (8-iso-PGF2alpha). Involved in the glucuronidation of the phytochemical ferulic acid at the phenolic or the carboxylic acid group. Location: Endoplasmic reticulum membrane; Cytoplasm, perinuclear region (UniProt). Locus 2q37.1 (HGNC).
