Sequence length	603 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. Has activity toward Muc5Ac and EA2 peptide substrates.
Catalytic activity	UDP-N-acetyl-alpha-D-galactosamine + polypeptide = UDP + N-acetyl-alpha-D-galactosaminyl-polypeptide. Ref.1
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.
Tissue specificity	Highly expressed in the sublingual gland, testis, small intestine, colon and ovary. Expressed at intermediate level in heart, brain, spleen, lung, stomach, cervix and uterus. Ref.1
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.
Caution	According to Ref.1, this enzyme is unable to transfer GalNAc onto serine or threonine residue on the protein receptor, but instead requires the prior addition of a GalNAc on a peptide before adding additional GalNAc moieties, thereby acting as a glycopeptide transferase. Was originally (Ref.1) termed Galnt9/pp-GaNTase 9.
