ANTI-OGT (C15-1452-820)

General description

OGT (O-linked N-acetylglucosamine transferase) gene is mapped to human chromosome Xq13.1. This gene encodes for nucleo cytosolic and mitochondrial isoforms of the enzyme. OGT is highly conserved among Caenorhabditis elegans, rat, and human genomes, sharing over 65% amino acid identity. The gene includes multiple tandem tetratricopeptide repeat sequences and is modified by O-GlcNA (O-linked N-acetylglucosamine), also by tyrosine phosphorylation.

Immunogen

O-linked N-acetylglucosamine (GlcNAc) transferase (UDP-N-acetylglucosamine:polypeptide-N-acetylglucosaminyl transferase) recombinant protein epitope signature tag (PrEST)

Application

All Prestige Antibodies^®Powered by Atlas Antibodies 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.

Biochem/physiol Actions

O-GlcNAc (O-linked N-acetylglucosamine) transferase (OGT) catalyzes O-GlcNAcylation that occurs in mitochondria, nuclear, and cytoplasmic proteins. O-GlcNAc transferase is a subunit of nonspecific lethal complex, a transcriptional regulator. O-GlcNAcylation involves the addition of O-GlcNAc to specific serine or threonine residue on many of the cytosolic and nuclear proteins. Disturbance in O-GlcNAcylation is associated with the development of diseases including cancer, diabetes, and Alzheimer disease. OGT is associated with increased mitochondrial respiration and elevated glycolysis. Inhibition in addition or removal of O-GlcNAc leads to a defect in preinitiation complex assembly.

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.

Linkage
