Description_x000D_ General description_x000D_ CECR1 (cat eye syndrome chromosome region, candidate 1) gene encodes a member of the family of adenosine deaminase growth factors (ADGFs) that have sequence similarity with classical adenosine deaminase (ADA) at the C-terminus. CECR1 is mainly expressed in fetal heart and kidney and in adult heart, lung and kidney. It contains an ADA (adenosine deaminase) domain and functions by regulating the level of extra-cellular adenosine. It is extensively glycosylated and contains a conserved disulfide bond and a signal peptide. This gene is mapped to human chromosome 22q11.2._x000D_ Immunogen_x000D_ Cat eye syndrome critical region protein 1 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_ CECR1 (cat eye syndrome chromosome region, candidate 1) is also called as ADA2 (adenosine deaminase 2) and plays a role in the degradation of extracellular adenosine, which acts as a signaling molecule in several cellular processes. ADA2 is secreted by differentiating monocytes and may function in the regulation of cell proliferation and differentiation. It is bound to the cell surface via proteoglycans and certain adenosine deaminase receptors. It promotes T cell-dependent differentiation of monocytes into macrophages and promotes proliferation of macrophages. It may serve as a drug candidate to regulate the immune responses during inflammation and cancer. Defects in this gene are associated with Cat eye syndrome and is responsible for some of the phenotype observed in this syndrome._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 APREST73541.
