GeneCards Summary for UGT2A3 Gene

UGT2A3 (UDP Glucuronosyltransferase Family 2 Member A3) is a Protein Coding gene. Among its related pathways are Drug metabolism - cytochrome P450 and Metabolism. Gene Ontology (GO) annotations related to this gene include carbohydrate binding and glucuronosyltransferase activity. An important paralog of this gene is UGT2A2.

UniProtKB/Swiss-Prot for UGT2A3 Gene

  • UDP-glucuronosyltransferases catalyze phase II biotransformation reactions in which lipophilic substrates are conjugated with glucuronic acid to increase water solubility and enhance excretion. They are of major importance in the conjugation and subsequent elimination of potentially toxic xenobiotics and endogenous compounds (By similarity).
