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.
Developmental stage	Broadly expressed in late embryonic and early postnatal cerebellar neurons, including premigratory granule neurons of the external granule cell layer. Expression is maintained in neurons of the internal granule cell layer after migration is complete. Expressed in Purkinje cells throughout development. Expressed in Bergmann glial scaffolds used by granule cells during early posnatal radial migration. Ref.5
Sequence similarities	Belongs to the glycosyltransferase 13 family.
