Description_x000D_ General description_x000D_ PITRM1 (Pitrilysin metallopeptidase 1) is a metalloendoprotease belonging to the pitrilysin family. It comprises of a conserved catalytic domain at the N-terminal region. It is highly expressed in the muscle, heart and lesser extent in the brain, pancreas, liver, lung, and placenta._x000D_ Immunogen_x000D_ Presequence protease, mitochondrial precursor recombinant protein epitope signature tag (PrEST)_x000D_ Application_x000D_ All Prestige Antibodies Powered by Atlas Antibodies are developed and validated by the Human Protein Atlas (HPA) project (www.proteinatlas.org)and as a result, are supported by the most extensive characterization in the industry._x000D_ 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.

LLC_x000D_ Biochem/physiol Actions_x000D_ PITRM1 (Pitrilysin metallopeptidase 1) acts as a mitochondrial amyloid-β peptide (Aβ)-degrading enzyme localized in the mitochondrial matrix. Its activity is controlled by Zn+2-dependent metalloprotease inhibitor. The temporal lobe of the human brain has a high tendency of Aβ accumulation and reactive oxygen species (ROS) production. In Alzheimer′s disease, the low proteolytic activity of PITRM1 in the brain mitochondria has been reported. Studies have been suggested that high ROS production results in decreased PITRM1 activity followed by Aβ accumulation. As a results, it leads to mitochondrial toxicity and neuronal death. Thus, it proves the impact of PITRM1 in the Alzheimer′s disease._x000D_ Features and Benefits_x000D_ 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._x000D_ Every Prestige Antibody is tested in the following ways:_x000D_ • IHC tissue array of 44 normal human tissues and 20 of the most common cancer type tissues._x000D_ • Protein array of 364 human recombinant protein fragments._x000D_ • Validated for multiple commonly used applications such as IHC (Immunohistochemistry), IF (Immunofluorescence), and WB (Western Blot)_x000D_ Linkage_x000D_ Corresponding Antigen APREST70796.
