GO Classification
Functions
drug binding / enzyme binding / enzyme inhibitor activity / glucuronosyltransferase activity / protein heterodimerization activity / protein homodimerization activity / protein kinase C binding / retinoic acid binding
Processes
cellular glucuronidation / cellular response to hormone stimulus / coumarin metabolic process / drug metabolic process / excretion / fatty acid metabolic process / flavone metabolic process / flavonoid biosynthetic process / flavonoid glucuronidation / negative regulation of catalytic activity / negative regulation of cellular glucuronidation / negative regulation of fatty acid metabolic process / negative regulation of glucuronosyltransferase activity / retinoic acid metabolic process / xenobiotic glucuronidation
Components
endoplasmic reticulum / endoplasmic reticulum membrane / integral component of membrane
General Function
Retinoic acid binding
Specific 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.
