Protein attributes

Sequence length	660 AA.
Sequence status	Complete.
Protein existence	Evidence at transcript level.

General annotation (Comments)

Function	Participates in O-mannosyl glycosylation. May be responsible for the synthesis of the GlcNAc(beta1-2)Man(alpha1-)O-Ser/Thr moiety on alpha-dystroglycan and other O-mannosylated proteins. Is specific for alpha linked terminal mannose By similarity.
Catalytic activity	UDP-N-acetyl-D-glucosamine + Man-R = N-acetyl-D-glucosamine-beta-1,2-Man-R + UDP.
Cofactor	Manganese By similarity.
Pathway	Protein modification; protein glycosylation.
Subcellular location	Golgi apparatus membrane; Single-pass type II membrane protein Potential.
Sequence similarities	Belongs to the glycosyltransferase 13 family.
