CC -!- FUNCTION: Glycopeptide transferase involved in O-linked oligosaccharide
CC biosynthesis, which catalyzes the transfer of an N-acetyl-D-
CC galactosamine residue to an already glycosylated peptide. In contrast
CC to other proteins of the family, it does not act as a peptide
CC transferase that transfers GalNAc onto serine or threonine residue on
CC the protein receptor, but instead requires the prior addition of a
CC GalNAc on a peptide before adding additional GalNAc moieties. Some
CC peptide transferase activity is however not excluded, considering that
CC its appropriate peptide substrate may remain unidentified (By
CC similarity). {ECO:0000250|UniProtKB:Q86SF2}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=L-seryl-[protein] + UDP-N-acetyl-alpha-D-galactosamine = 3-O-
CC [N-acetyl-alpha-D-galactosaminyl]-L-seryl-[protein] + H(+) + UDP;

CC -!- COFACTOR:
CC Name=Mn(2+); Xref=ChEBI:CHEBI:29035; Evidence={ECO:0000250};
CC -!- PATHWAY: Protein modification; protein glycosylation.
CC {ECO:0000250|UniProtKB:Q86SF2}.
CC -!- SUBCELLULAR LOCATION: Golgi apparatus membrane {ECO:0000250}; Single-
CC pass type II membrane protein {ECO:0000250}.
CC -!- DOMAIN: There are two conserved domains in the glycosyltransferase
CC region: the N-terminal domain (domain A, also called GT1 motif), which
CC is probably involved in manganese coordination and substrate binding
CC and the C-terminal domain (domain B, also called Gal/GalNAc-T motif),
CC which is probably involved in catalytic reaction and UDP-Gal binding.
CC {ECO:0000250}.
CC -!- DOMAIN: The ricin B-type lectin domain binds to GalNAc and contributes
CC to the glycopeptide specificity. {ECO:0000250}.
CC -!- SIMILARITY: Belongs to the glycosyltransferase 2 family. GalNAc-T
CC subfamily. {ECO:0000305}.
