Anti-GALNT8 antibody produced in rabbit

HPA012638    Human Protein Atlas characterization data

Polypeptide GalNAc transferase 8 (GALNT8) is a type-II membrane protein which belongs to the UDP-GalNAc:polypeptide N-acetylgalactosaminyltransferase (ppGaNTase) family. The gene is present on chromosome 12p13.3 and encodes 637 amino acids.

All Prestige Antibodies Powered by Atlas Antibodies are developed and validated by the Human Protein Atlas (HPA) project (www.proteinatlas.org)and as a result, are supported by the most extensive characterization in the industry.

The Human Protein Atlas project can be subdivided into three efforts: Human Tissue Atlas, Cancer Atlas, and Human Cell Atlas. The antibodies that have been generated in support of the Tissue and Cancer Atlas projects have been tested by immunohistochemistry against hundreds of normal and disease tissues and through the recent efforts of the Human Cell Atlas project, many have been characterized by immunofluorescence to map the human proteome not only at the tissue level but now at the subcellular level. These images and the collection of this vast data set can be viewed on the Human Protein Atlas (HPA) site by clicking on the Image Gallery link. To view these protocols and other useful information about Prestige Antibodies and the HPA, visit sigma.com/prestige.

Polypeptide GalNAc transferase 8 (GALNT8) initiates mucin-like O-glycosylation of specific target proteins and transfers GalNAc to serine and threonine residues on target proteins in the Golgi apparatus. Hence it takes part in the biosynthesis of mucin-like O-glycans. It may modulate the signal transduction of IFN (Interferon)-α-mediated antiviral activity. The overexpression of GALNT8 weakens the IFN-α-induced gene transcription via the IFN-stimulated response element. Thus, it is linked with the response to IFN therapy against chronic hepatitis C (CHC).

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.
