Protein attributes

Sequence length	523 AA.
Sequence status	Complete.
Sequence processing	The displayed sequence is further processed into a mature form.
Protein existence	Evidence at transcript level.

General annotation (Comments)

Function	UDP-glucuronosyltransferases catalyze phase II biotransformation reactions in which lipophilic substrates are conjugated with glucuronic acid to increase water solubility and enhance excretion. They are of major importance in the conjugation and subsequent elimination of potentially toxic xenobiotics and endogenous compounds By similarity.
Catalytic activity	UDP-glucuronate + acceptor = UDP + acceptor beta-D-glucuronoside.
Subcellular location	Membrane; Single-pass type I membrane protein Potential.
Sequence similarities	Belongs to the UDP-glycosyltransferase family.
