General annotation (Comments)

Function	Beta-1,3-galactosyltransferase that transfers galactose from UDP-galactose to substrates with a terminal beta-N-acetylglucosamine (beta-GlcNAc) residue. Involved in the biosynthesis of N-glycans containing Lewis a structures (with the combination of FUT13). Ref.1
Cofactor	Manganese. Ref.1
Pathway	Protein modification; protein glycosylation.
Subcellular location	Golgi apparatus membrane; Single-pass type II membrane protein. Ref.1
Tissue specificity	Expressed in stems and siliques. Ref.1
Sequence similarities	Belongs to the glycosyltransferase 31 family. Contains 1 galectin domain.
Sequence caution	The sequence AAF87039.1 differs from that shown. Reason: Erroneous gene model prediction.
