    basic FUNCTION
  • ecto-nucleosidases that hydrolyze 5'-triphosphates
  • by regulating angiogenesis and inflammation, seems to play an important role in tumor progression
  • expressed at a much lower level than ENTPD5, but was also elevated in PTEN null cells
  • cellular homeostasis and fibrotic response involve the integration of signaling that is pro-fibrotic by ATP and anti-fibrotic by adenosine and that is regulated by ENTPD1 and ENTPD2
  • ectoenzyme that hydrolyzes extracellular nucleoside di- and triphosphates
  • has functionality in scavenging mitogenic extracellular nucleoside triphosphates in neurogenic niches of the adult brain, thereby acting as a homeostatic regulator of nucleotide-mediated neural progenitor cell proliferation and expansion
