Protein attributes

Sequence length	528 AA.
Sequence status	Complete.
Sequence processing	The displayed sequence is further processed into a mature form.
Protein existence	Evidence at protein level.

General annotation (Comments)

Function	UDPGTs are of major importance in the conjugation and subsequent elimination of potentially toxic xenobiotics and endogenous compounds. This isozyme is active on polyhydroxylated estrogens (such as estriol, 4-hydroxyestrone and 2-hydroxyestriol) and xenobiotics (such as 4-methylumbelliferone, 1-naphthol, 4-nitrophenol, 2-aminophenol, 4-hydroxybiphenyl and menthol). It is capable of 6 alpha-hydroxyglucuronidation of hyodeoxycholic acid.
Catalytic activity	UDP-glucuronate + acceptor = UDP + acceptor beta-D-glucuronoside.
Subcellular location	Microsome membrane; Single-pass membrane protein Potential. Endoplasmic reticulum membrane; Single-pass membrane protein Potential.
Sequence similarities	Belongs to the UDP-glycosyltransferase family.
Caution	Ref.2 thought that this was a new form (UGT2B11). The name UGT2B11 has now been reused for another human enzyme.
