Gene Information

human ... CASP3(836)

General description

CASP3 (caspase 3), the allosteric regulator, is a member of the cysteine-aspartic acid protease (caspase) family which is involved in the inflammation and mammalian apoptosis. It consists of binding sites for small molecules and peptides.

Anti-CASP3 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.

Biochem/physiol Actions

CASP3 (caspase 3) may have an impact on the melanoma tumor growth after the cytotoxic therapy. It plays a vital role in the proliferation of surrounding cells during executioner phase of apoptosis. Caspases are synthesized and localized as inactive zymogens. After a cascade of proteolytic processing they get activated. Upon activation, they cleave into two separate subunits which further dimerize to form the active enzyme. The activity of caspase-3 is induced by the accumulation of reactive oxygen species (ROS), mitochondrial dysfunction and reduction in adenosine triphosphate (ATP) levels. Alteration in the CASP3 gene is associated with neuronal death in Alzheimer′s disease.

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.
