CD73, also known as 5’-NT, NT5 and NTE, is a glycosyl-phosphatidyl-inositol (GPI) anchored cell membrane protein that belongs to the 5'-nucleotidase (5’-NT) family. The native enzyme exists as a homodimer on the cell surface. CD73 is a purine salvage enzyme expressed on human T and B lymphocytes. CD73 converts extracellular nucleoside­5'­monophosphates to membrane permeable nucleosides, with AMP as the preferred substrate. It also exhibits AMP-, NAD-, and NMN-nucleosidase activities.  CD73 is one of several ectoenzymes responsible for the production of extracellular adenosine, a signaling molecule involved in many physiologic processes, including inflammation, tissue injury response, and cholinergic synapses. CD73 produces extracellular adenosine, which then acts on G protein-coupled purigenic receptors (GPCR) to induce intracellular responses. CD73 is also a regulator of leukocyte extravasation, a function that requires its 5'­nucleotidase activity. CD73 mediates lymphocyte-stromal cell interactions to facilitate lymphocyte development/function.  CD73 has also been considered as a lymphocyte maturation marker independent of its catalytic activity. CD73 serves as a co-stimulatory molecule in activating T cells. The mutation in CD73 gene is associated with calcification of joints and arteries (CALJA), a condition characterized by adult-onset calcification of the lower extremity arteries  and hand and foot capsule joints.

Primers: Gene insert coding sequence can be confirmed by following primers:

(a) forward (or 5'-end) primer: 5’-CAAATGGGCGGTAGGCGTG-3’;

(b) reverse (or 3'-end) primer: 5’-CCAGGTTTCCGGGCCCTCAC-3’

 

 

Note: The sequence may vary due to the naturally occurring variants or mutations, such as single nucleotide polymorphism, or the artifact during PCR amplification.  High fidelity PCR systems should always be used.
