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. Although it displays a much weaker activity toward all substrates tested compared to GALNT2, it is able to transfer up to seven GalNAc residues to the Muc5AC peptide, suggesting that it can fill vicinal Thr/Ser residues in cooperation with other GALNT proteins. Prefers Muc1a as substrate 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.

Tissue specificity

Specifically expressed in testis. Ref.3

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.
