Protein attributes

Sequence length	622 AA.
Sequence status	Complete.
Protein existence	Evidence at transcript level

General annotation (Comments)

Function	Catalyzes the initial reaction in O-linked oligosaccharide biosynthesis, the transfer of an N-acetyl-D-galactosamine residue to a serine or threonine residue on the protein receptor. May participate in synthesis of oncofetal fibronectin. Has activity toward Muc1a, Muc2, EA2 and fibronectin peptides By similarity.
Catalytic activity	UDP-N-acetyl-alpha-D-galactosamine + polypeptide = UDP + N-acetyl-alpha-D-galactosaminyl-polypeptide.
Cofactor	Manganese By similarity. Calcium By similarity.
Pathway	Protein modification; protein glycosylation.
Subcellular location	Golgi apparatus membrane; Single-pass type II membrane protein By similarity.
Domain	There are two conserved domains in the glycosyltransferase region: the N-terminal domain (domain A, also called GT1 motif), which is probably involved in manganese coordination and substrate binding and the C-terminal domain (domain B, also called Gal/GalNAc-T motif), which is probably involved in catalytic reaction and UDP-Gal binding By similarity. The ricin B-type lectin domain binds to GalNAc and contributes to the glycopeptide specificity By similarity.
Sequence similarities	Belongs to the glycosyltransferase 2 family. GalNAc-T subfamily. Contains 1 ricin B-type lectin domain.
Sequence caution	The sequence CAB55352.1 differs from that shown. Reason: Frameshift at position 622.
