Anti-Recombinant CD39, clone A701

CD39,also known as ectonucleoside triphosphate diphosphohydrolase 1 (NTPDase 1), is a multi-pass membrane ectoenzyme that metabolizes adenosine-5'-triphosphate (ATP) to regulate purinergic signaling. Purinergic signaling by extracellular ATP and its metabolites regulate many biological processes, including vascular tone, digestion, neuronal function, and inflammation in both normal and diseased states. CD39 is expressed in endothelial cells in the vasculature to regulate local platelet purinergic signaling via metabolism of ATP to adenosine. Accordingly, CD39 regulates platelet activation aggregation and contributes to the antithrombotic properties of endothelial cells. ATP and its metabolites also finely modulate the activity of T cells and macrophages. Immunomodulation is regulated, in part, by the availability of extracellular ATP and adenosine, suggesting that CD39 may play an immunosuppressive role in the tumor microenvironment.
