CD39/ENTPD1: Proteins and Enzymes

Ectonucleoside triphosphate diphosphohydrolase-1 (ENTPD1 or NTPDase-1, also called ecto-apyrase, designated CD39) is a transmembrane glycoprotein that hydrolyzes the alpha- and beta phosphate residues of extracellular ATP or ADP. It is expressed on B, T and NK cells, and some endothelial cells, and helps regulate platelet activation, vascular inflammation, and cardiac norepinephrine release.
