text
  • bounds by a glycosyl phosphatidyl inositol linkage to the external face of the plasma membrane
  • expressed on normal and neoplastic glial plasma membranes (Ludwig et al, 1999)
  • basic FUNCTION
  • cell surface enzyme of the purine catabolic pathway that catalyzes the breakdown of AMP to adenosine
  • hydrolyzing extracellular nucleotides into membrane permeable nucleosides
  • may facilitate the adhesion, migration and invasion of human breast cancer cells through its enzyme activity of generating adenosine
  • required for the efficient entry of lymphocytes into the CNS during experimental autoimmune encephalomyelitis development
  • novel and specific receptor for tenascin C and the interaction between these proteins may influence cell adhesion and migration and also lead to decreased generation of local adenosine (Sadej 2008)
  • a signalling pathway metabolite in the immune response of lymphocytes
  • a cell surface marker of cone/rod common precursors and mature rod cells genetically localized between Nrl and Crx (Koso 2009)
  • extracellular adenosine, generated in tandem by ecto-enzymes ENTPD1 and NT5E, promotes dermal fibrogenesis
  • ENTPD1, NT5E are two ectonucleotidases that cooperate in the generation of extracellular adenosine through ATP hydrolysis, thus tilting the balance towards immunosuppressive microenvironments
  • CELLULAR PROCESS
    PHYSIOLOGICAL PROCESS
    text catalyzes the conversion at neutral pH of purine 5-prime mononucleotides to nucleosides
    PATHWAY
    metabolism purine/pyrimidine
    signaling
    nucleotide
    a component
  • glycoprotein constituent of membrane (Pi linked)
  • component of multiresistance machinery, the transcription of which is activated under selective pressure of the immune system (Ludwig et al, 1999)
  • INTERACTION
    DNA
    RNA
    small molecule cofactor,

    protein

    ANIMAL & CELL MODELS
  • ecto-5'-nucleotidase/CD73-deficient mice have a significantly reduced fall in stop flow pressure and superficial nephron glomerular filtration rate in response to a saturating increase of tubular perfusion flow (Castrop et al, 2004)
