General description

Polypeptide N-acetylgalactosaminyltransferase 1 (GALNT1) is localized to the Golgi apparatus. The gene encoding this protein is present on chromosome 18q12-q21.


polypeptide N-acetylgalactosaminyltransferase 1

Biochem/physiol Actions

Polypeptide N-acetylgalactosaminyltransferase 1 (GALNT1) is involved in catalyzing the initial reaction of O-linked oligosaccharide biosynthesis. It has a wide range of protein substrates. GALNT1 transfers an N-acetyl-D-galactosamine residue to a serine or threonine residue which is present on the protein substrate.

Features and Benefits

Prestige Antibodies® are highly characterized and extensively validated antibodies with the added benefit of all available characterization data for each target being accessible via the Human Protein Atlas portal linked just below the product name at the top of this page. The uniqueness and low cross-reactivity of the Prestige Antibodies® to other proteins are due to a thorough selection of antigen regions, affinity purification, and stringent selection. Prestige antigen controls are available for every corresponding Prestige Antibody and can be found in the linkage section.

Every Prestige Antibody is tested in the following ways:
  • IHC tissue array of 44 normal human tissues and 20 of the most common cancer type tissues.
  • Protein array of 364 human recombinant protein fragments.

O-glycosylation of proteins is initiated by a family of UDP-N-acetylgalactosamine:polypeptide N-acetylgalactos-aminyltransferases (GalNAc-T). In this study, we have localized endogenous and epitope-tagged human GalNAc-T1, -T2 and -T3 to the Golgi apparatus in HeLa cells by subcellular fractionation, immunofluorescence and immunoelectron microscopy....

Mucin-type O-glycosylation is initiated by UDP-N-acetylgalactosamine:polypeptide N-acetylgalactosaminyltransferases (GalNAc-transferases). The role each GalNAc-transferase plays in O-glycosylation is unclear. In this report we characterized the specificity and kinetic properties of three purified recombinant GalNAc-transferases. GalNAc-T1, -T2, and -T3 were expressed as soluble...

A homologous family of UDP- N -acetylgalactosamine: polypeptide N -acetylgalactosaminyltransferases (GalNAc-transferases) initiate O-glycosylation. These transferases share overall amino acid sequence similarities of approximately 45-50%, but segments with higher similarities of approximately 80% are found in the putative catalytic domain. Here...
