Application Abreviews Notes
ELISA Use at an assay dependent concentration.

ELISA titre using peptide based assay: 1/12500.

WB Use a concentration of 1 µg/ml. Predicted molecular weight: 67 kDa. Good results were obtained when blocked with 5% non-fat dry milk in 0.05% PBS-T.


  • FunctionCatalyzes 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 a highest activity toward Muc7, EA2 and Muc2, with a lowest activity than GALNT2. Glycosylates 'Thr-57' of SELPLG.
  • Tissue specificityUbiquitous. Highly expressed in mucous cells.
  • PathwayProtein modification; protein glycosylation.
  • Sequence similaritiesBelongs to the glycosyltransferase 2 family. GalNAc-T subfamily.
    Contains 1 ricin B-type lectin domain.
  • DomainThere 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.
    The ricin B-type lectin domain directs the glycopeptide specificity. It is required in the glycopeptide specificity of enzyme activity but not for activity with naked peptide substrates, suggesting that it triggers the catalytic domain to act on GalNAc-glycopeptide substrates.
