Description_x000D_ General description_x000D_ NT5E (5′-nucleotidase, ecto, CD73) is a glycosyl-phosphatidylinositol-linked plasma membrane glycoprotein encoding a protein, ecto-5′-nucleotidase (CD73), which acts as the major enzymatic source of extracellular adenosine. It is expressed in different types of cells and in different tissues._x000D_ Immunogen_x000D_ 5′-nucleotidase precursor recombinant protein epitope signature tag (PrEST)_x000D_ Application_x000D_ Anti-NT5E antibody produced in rabbit, a Prestige Antibody, is developed and validated by the Human Protein Atlas (HPA) project (www.proteinatlas.org). 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.

LLC_x000D_ Biochem/physiol Actions_x000D_ NT5E (5′-nucleotidase, ecto, CD73) plays an important role in the stabilization of tissue homeostasis and controlling of several pathophysiologic responses related to immunity, inflammation, pain, ischemia, tissue fibrosis, and cancer. It is involved in the generation of adenosine from degradation of AMP (adenosine monophosphate) in the extracellular environment. CD73 facilitates the conversion of intracellular AMP to adenosine, which further regulates various processes by activating one of four subtypes of G-protein-coupled receptors. Mutation in NT5E causes an adult-onset condition characterized by joint pain, calcification of joints and arteries (CALJA)._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 APREST72880.
