General annotation (Comments)

Function

Can initiate the synthesis or the elongation of the linear poly-N-acetyllactosaminoglycans. Involved in alpha-dystroglycan (DAG1) glycosylation By similarity.

Catalytic activity

UDP-N-acetyl-D-glucosamine + beta-D-galactosyl-(1->4)-N-acetyl-D-glucosaminyl-R = UDP + N-acetyl-beta-D-glucosaminyl-(1->3)-beta-D-galactosyl-(1->4)-N-acetyl-D-glucosaminyl-R.

Pathway

Protein modification; protein glycosylation.

Subcellular location

Golgi apparatus membrane; Single-pass type II membrane protein By similarity.

Sequence similarities

Belongs to the glycosyltransferase 49 family.

Sequence caution

The sequence AAX46482.1 differs from that shown. Reason: Frameshift at position 387.
