CD73 Recombinant Mouse Monoclonal Antibody [A6G2-R]

Function :
5′-nucleotidase (5′-NT), also known as ecto-5′-nucleotidase or CD73 (cluster of differentiation 73), is an enzyme that in humans is encoded by the NT5E gene. CD73 commonly serves to convert AMP to adenosine. Ecto-5-prime-nucleotidase catalyzes the conversion at neutral pH of purine 5-prime mononucleotides to nucleosides, the preferred substrate being AMP.{{FIPI} medchemexpress|{FIPI} Autophagy|{FIPI} Biological Activity|{FIPI} Description|{FIPI} custom synthesis|{FIPI} Autophagy} The enzyme consists of a dimer of 2 identical 70-kD subunits bound by a glycosyl phosphatidyl inositol linkage to the external face of the plasma membrane.{{Abciximab} web|{Abciximab} Integrin|{Abciximab} Purity & Documentation|{Abciximab} In Vitro|{Abciximab} supplier|{Abciximab} Cancer} The enzyme is used as a marker of lymphocyte differentiation.PMID:24580853 Consequently, a deficiency of NT5 occurs in a variety of immunodeficiency diseases. Other forms of 5-prime nucleotidase exist in the cytoplasm and lysosomes and can be distinguished from ecto-NT5 by their substrate affinities, requirement for divalent magnesium ion, activation by ATP, and inhibition by inorganic phosphate. Rare allelic variants are associated with a syndrome of adult-onset calcification of joints and arteries (CALJA) affecting the iliac, femoral, and tibial arteries reducing circulation in the legs and the joints of the hands and feet causing pain. NT5E can act as an immune inhibitory control molecule. Free adenosine generated by NT5E inhibits cellular immune responses and thereby promotes immune escape of tumor cells.
