Function

Function:
UDPGT is of major importance in the conjugation and subsequent elimination of potentially toxic xenobiotics and endogenous compounds. Isoform 2 lacks transferase activity but acts as a negative regulator of isoform 1.
Catalytic Activity:
UDP-glucuronate + acceptor = UDP + acceptor beta-D-glucuronoside.
