Ectonucleotide pyrophosphatase/phosphodiesterase 5 (ENPP-5 or NPP5) belongs to a group of ecto-enzymes which regulate the availability of extracellular nucleotides. This enzyme family forms a subgroup of a larger family that also includes arylsulfatases, phosphopentomutases, 2,3-bisphosphoglycerate-independent phosphoglycerate mutases (iPGM), and alkaline phosphatases. Mature human ENPP-5 is an approximately 50 kDa protein that consists of a 407 amino acid (aa) extracellular region with one phosphodiesterase/nucleotide pyrophosphatase domain, a 21 aa transmembrane segment, and a 25 aa cytoplasmic tail. Within the ectodomain, human ENPP-5 shares 85% aa sequence identity with mouse and rat ENPP-5. R&D Systems in-house testing indicates that recombinant human ENPP-5 exhibits phosphodiesterase activity with the substrate O-(4-Nitrophenylphosphoryl) choline.
Post-translational: N-glycosylated.
