ENTPD2 encodes the human gene, Ectonucleoside triphosphate diphosphohydrolase 2. It may also be known as: NTPDase 2; CD39 antigen-like 1; Ecto-ATP diphosphohydrolase 2; Ecto-ATPDase 2; Ecto-ATPase 2; CD39-like-1; ecto-ATPase; CD39L1; NTPDase-2. The encoded protein is an enzyme with an amino acid length of 495 and a mass of 53.7 kDa. Other isoforms may exist. ENTPD2 is a member of the GDA1/CD39 NTPase family. Homologs of this gene exist in other organisms, including: Mouse, Rat, Frog, Chicken.
