ANTI-GALNT2

General description

GALNT2 (polypeptide N-acetylgalactosaminyltransferase 2) belongs to the ppGalNAc-T family, and is a type II transmembrane protein. The catalytic domain resides in the Golgi luminal region, and the R-type lectin domain lies in the C-terminal. This gene is localized to human chromosome 1q41-q42.

Immunogen

polypeptide N-acetylgalactosaminyltransferase 2

Application

Anti-GALNT2 antibody produced in rabbit, a Prestige Antibody, is developed and validated by the Human Protein Atlas (HPA) project . Each antibody is tested by immunohistochemistry against hundreds of normal and disease tissues. These images can be viewed on the Human Protein Atlas (HPA) site by clicking on the Image Gallery link. The antibodies are also tested using immunofluorescence and western blotting. To view these protocols and other useful information about Prestige Antibodies and the HPA, visit sigma.com/prestige.

Biochem/physiol Actions

GALNT2 (polypeptide N-acetylgalactosaminyltransferase 2) catalyzes the first step of O-linked glycosylation of proteins. It is responsible for the attachment of first N-acetylgalactosamine (GalNAc) monosaccharide to the protein. The expression of this gene is up-regulated in cancers, and it might be involved in tumorigenesis. It suppresses the expression of matrix metalloproteinase (MMP)-2 and transforming growth factor (TGF)-β1, and thus prevents proliferation and metastasis of gastric cancer cells. It modulates the development of placenta by regulating extravillus trophoblast (EVT) invasion. GALNT2 is also involved in insulin homeostasis by regulating the expression of ENPP1 (ectonucleotide pyrophosphatase), which is an inhibitor of insulin receptor signaling. Its expression is reduced in type 2 diabetes patients, and thus, it might play a role in hyperglycemia. It is up-regulated in oral squamous cell carcinoma (OSCC), and enhances the invasiveness of OSCC by modulating the O-glycosylation and activity of EGFR (epidermal growth factor receptor).

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.
