General annotation (Comments)

Function

Catalyzes the transfer of a single N-acetylglucosamine from UDP-GlcNAc to a serine or threonine residue in extracellular proteins resulting in their modification with a beta-linked N-acetylglucosamine (O-GlcNAc). Specifically glycosylates the Thr residue located between the fifth and sixth conserved cysteines of folded EGF-like domains By similarity.

Catalytic activity

UDP-N-acetyl-D-glucosamine + [protein]-L-serine = UDP + [protein]-3-O-(N-acetyl-D-glucosaminyl)-L-serine.

UDP-N-acetyl-D-glucosamine + [protein]-L-threonine = UDP + [protein]-3-O-(N-acetyl-D-glucosaminyl)-L-threonine.

Subcellular location

Endoplasmic reticulum lumen By similarity.

Sequence similarities

Belongs to the glycosyltransferase 61 family.
