Protein

UDP-glucuronosyltransferase 2B28

Gene

UGT2B28

Organism
Homo sapiens (Human)
Status
Reviewed-Annotation score: -Experimental evidence at protein leveli

Functioni

UDPGTs are of major importance in the conjugation and subsequent elimination of potentially toxic xenobiotics and endogenous compounds. This isozyme has glucuronidating capacity with steroid substrates such as 5-beta-androstane 3-alpha,17-beta-diol, estradiol, ADT, eugenol and bile acids. Only isoform 1 seems to be active.1 Publication

Catalytic activityi

UDP-glucuronate + acceptor = UDP + acceptor beta-D-glucuronoside.1 Publication
