Protein existence	Evidence at transcript level

General annotation (Comments)

Function	Beta-1,3-galactosyltransferase that transfers galactose from UDP-galactose to substrates with a terminal glycosyl residue By similarity.
Cofactor	Manganese By similarity.
Pathway	Protein modification; protein glycosylation.
Subcellular location	Golgi apparatus membrane; Single-pass type II membrane protein Probable.
Sequence similarities	Belongs to the glycosyltransferase 31 family.
Sequence caution	The sequence AAC31227.1 differs from that shown. Reason: Erroneous gene model prediction.
