Protein attributes

Sequence length	376 AA.
Sequence status	Complete.
Sequence processing	The displayed sequence is not processed.
Protein existence	Evidence at transcript level.

General annotation (Comments)

Function	Transfer of galactose from UDP-galactose to an acceptor molecule (R).
Catalytic activity	UDP-galactose + beta-D-galactosyl-(1->4)-beta-N-acetyl-D-glucosaminyl-R = UDP + alpha-D-galactosyl-(1->3)-beta-D-galactosyl-(1->4)-beta-N-acetylglucosaminyl-R.
Cofactor	Manganese By similarity.
Pathway	Protein modification; protein glycosylation.
Subcellular location	Golgi apparatus › Golgi stack membrane; Single-pass type II membrane protein By similarity. Note: Membrane-bound form in trans cisternae of Golgi By similarity.
Domain	The conserved DXD motif is involved in cofactor binding. The manganese ion interacts with the beta-phosphate group of UDP and may also have a role in catalysis By similarity.
Sequence similarities	Belongs to the glycosyltransferase 6 family.
