Background: CD39/ENTPD1

CD39, also known as ectonucleoside triphosphate diphosphohydrolase-1 (NTPDase-1), is the prototypical member of the NTPDase family. CD39 is a metal-dependent, homodimeric enzyme bound to the cell membrane through two transmembrane domains present at each termini (1-3). The extracellular loop contains two major domains with an active site and apyrase conserved regions (ACRs) and changes conformation dynamically during catalysis (1-4). Although first described as a B lymphocyte cell surface marker (5), CD39 is also present on the surface of natural killer cells, T cells, and some endothelial cells (6). CD39 hydrolyzes the beta - and gamma  phosphate residues of nucleotides to terminate purinergic signaling and is uniquely capable of processive hydrolysis of extracellular ATP to AMP without release of the ADP intermediate (3, 7, 8) as the initial rate-limiting steps in the production of extracellular adenosine (9). CD39 functional activity leads to interest in CD39 as a pharmaceutical therapeutic target for several disease models including inflammation, cancer, and immunosuppression (3,4,9,10). Recombinant cynomolgus NTPDase-1 was expressed as a protein lacking its N- and C-terminal transmembrane domains, resulting in the secretion of the soluble recombinant NTPDase-1 ectodomain.
