CD39L2/ENTPD6 Products

CD39L2, also known as ectonucleoside triphosphate diphosphohydrolase-6 (ENTPD-6) and NTPDase-6, is a nucleoside phosphohydrolase of the CD39 family of enzymes that is present on the surface of cells. This Type II membrane protein also exists as a soluble, secreted protein. CD39L2 displays a preference for the nucleoside-5'-diphosphates GDP and IDP over CDP and UDP. Nucleoside-5'-triphosphates are also hydrolyzed, but at much lower rates. CD39L2 is expressed at its highest levels in cardiac muscle and in heart capillary endothelial cells. CD39L2 may play a functional role in the regulation and recruitment of platelet activation in the heart. The cytoplasmic and transmembrane domains of rmCD39L2 were replaced with a signal sequence, resulting in the secretion of the recombinant protein.
