ANTI-SIRT5 (C15-1450-203)

General description

The gene SIRT5 (sirtuin 5) is mapped to human chromosome 6p23. It is mainly expressed in brain, testis, heart muscle cells, and lymphoblasts. SIRT5 belongs to the sirtuins family of NAD (nicotinamide adenine dinucleotide)-dependent lysine deacylases. The protein is present in the mitochondria.

Immunogen

NAD-dependent deacetylase sirtuin-5 recombinant protein epitope signature tag (PrEST)

Application

All Prestige Antibodies Powered by Atlas Antibodies are developed and validated by the Human Protein Atlas (HPA) project 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. We also provide Prestige Antibodies^® protocols and other useful information.

Biochem/physiol Actions

Sirtuins (SIRTs) are responsible for the removal of acetyl groups from modified lysine residues in proteins. SIRT5 uses malonyllysine, succinyllysine, and glutaryllysine as substrates. It can also enhance mitochondrial respiration and cellular metabolism in the presence of excess glucose. SIRT5 is involved in the activation of SOD1 (superoxide dismutase 1) by desuccinylation, leading to elimination of reactive oxygen species. It also participates in caloric restriction effects by deacetylation of CPS1 (carbamoyl phosphate synthetase 1).

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

Corresponding Antigen APREST73828.

Physical form

Solution in phosphate-buffered saline, pH 7.2, containing 40% glycerol and 0.02% sodium azide
