Gene Information

human ... SIRT4(23409)

General description

SIRT4 (sirtuin 4) belongs to sirtuin family of nicotinamide adenine dinucleotide-dependent enzymes. It is a NAD+-dependent ADP ribosyltransferase, that is located in the mitochondria. SIRT4 protein level is found to be more in ESCC (esophageal squamous cell carcinoma) tissues.

Immunogen

sirtuin (silent mating type information regulation 2 homolog) 4 (S. cerevisiae) recombinant protein epitope signature tag (PrEST)

Application

Anti-SIRT4 has been used in immunohistochemistry.

Biochem/physiol Actions

SIRT4 (sirtuin 4) may involve in the development of esophageal cancer. Growth of HeLa cells can be suppressed by the overexpression of SIRT4. It modulates glutamine metabolism and may also act as a tumor suppressor. It plays some important roles in multiple cellular processes like stress response and longevity. It may act as an important therapeutic target in colorectal cancer.

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 APREST78151

Physical form

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

The sirtuins (SIRTs) are a family of nicotinamide-adenine dinucleotide (NAD)+-dependent protein deacetylases. SIRT4 is a mitochondrial NAD+-dependent adenosine diphsophate-ribosyltransferase. Recent studies demonstrated that SIRT4 can regulate glutamine metabolism and thus act as a tumor suppressor. However, the association of SIRT4
