General description

IFI16 (γ-interferon-inducible protein 16) is a member of the PYRIN superfamily and HIN-200 family (hematopoietic interferon-inducible nuclear antigens with 200 amino acid repeat) which is involved in the p53-mediated regulation of apoptosis and inflammation signaling pathways. It is highly expressed in endothelial cells and squamous stratified epithelia. It is found in the nuclei of lymphocytes in the spleen, thymus, lymph nodes, palatine tonsil and non-lymphoid tissues including trachea, gastrointestinal tract, skin and testis. IFI16 is composed of a DNA binding domain, a transcriptional regulatory domain, DAPIN (domain in apoptosis and interferon response) domain associated with interferon (IFN) response and BRCA1 binding domain (breast cancer tumor suppressor protein).

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

IFI16 (γ-interferon-inducible protein 16) is involved in the regulation of p53-mediated gene transcription. It acts as a potent transcription repressor. It stimulates p53-mediated apoptosis under DNA damage conditions. Along with p53, it also regulates other target genes such as p21, HDM2 (E3 ubiquitin-protein ligase), and BAX (apoptosis regulator) in MCF7 cells.

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.
