UDP-glucuronosyltransferase 2A3 (UGT2A3)

Target
UGT2A3
Molecular classification
Enzyme, Transferase, Phase II drug-metabolizing enzyme
01

Overview

UGT2A3 is a membrane-bound phase II drug-metabolizing enzyme that catalyzes the glucuronidation of various lipophilic substrates to facilitate their elimination. It contains distinct substrate-binding and UDP-glucuronic acid-binding domains and can form oligomeric complexes that modulate enzymatic activity. The enzyme plays a crucial role in xenobiotic metabolism and drug clearance pathways.
