CC -!- FUNCTION: UDP-glucuronosyltransferase (UGT) that catalyzes phase II
CC biotransformation reactions in which lipophilic substrates are
CC conjugated with glucuronic acid to increase the metabolite's water
CC solubility, thereby facilitating excretion into either the urine or
CC bile. Essential for the elimination and detoxification of drugs,
CC xenobiotics and endogenous compounds. Catalyzes the glucuronidation of
CC endogenous estrogen hormone estradiol. Contributes to bile acid (BA)
CC detoxification by catalyzing the glucuronidation of BA substrates,
CC which are natural detergents for dietary lipids absorption. Potential
CC role in detoxification of toxic waste compounds in the amniotic fluid
CC before birth, and air-born chemical after birth.

CC -!- SUBCELLULAR LOCATION: Membrane {ECO:0000250|UniProtKB:Q9Y4X1}; Single-
CC pass type I membrane protein {ECO:0000255}.
CC -!- MISCELLANEOUS: UGT2A2 isoform is part of the UGT2A complex locus which
CC displays alternative use of promoters and exons. The locus is defined
CC by 2 alternative promoters resulting in 2 fonctionally active
CC polypeptides UGT2A1 and UGT2A2. Alternative splicing of exons results
CC in additional isoforms for each protein class.
CC {ECO:0000250|UniProtKB:P0DTE5}.
CC -!- SIMILARITY: Belongs to the UDP-glycosyltransferase family.
CC {ECO:0000305}.
