Comments
  • FUNCTION: Involved primarily in ATP hydrolysis at the plasma membrane. Plays a role in regulating pyrophosphate levels, and functions in bone mineralization and soft tissue calcification. In vitro, has a broad specificity, hydrolyzing other nucleoside 5' triphosphates such as GTP, CTP, TTP and UTP to their corresponding monophosphates with release of pyrophosphate and diadenosine polyphosphates, and also 3',5'-cAMP to AMP. May also be involved in the regulation of the availability of nucleotide sugars in the endoplasmic reticulum and Golgi, and the regulation of purinergic signaling. Appears to modulate insulin sensitivity.
  • CATALYTIC ACTIVITY: Hydrolytically removes 5'-nucleotides successively from the 3'-hydroxy termini of 3'-hydroxy-terminated oligonucleotides.
  • CATALYTIC ACTIVITY: A dinucleotide + H2O = 2 mononucleotides.
  • COFACTOR: Binds 2 divalent metal cations per subunit (Probable).
  • ENZYME REGULATION: At low concentrations of ATP, a phosphorylated intermediate is formed which inhibits further hydrolysis.
  • SUBUNIT: Homodimer; disulfide-linked.
  • SUBCELLULAR LOCATION: Membrane; Single-pass type II membrane protein. Note=Targeted to the basolateral membrane in polarized epithelial cells and in hepatocytes, and to matrix vesicles in osteoblasts. In bile duct cells and cancer cells, located to the apical cytoplasmic side.
  • TISSUE SPECIFICITY: Expressed in plasma cells and also in a number of non-lymphoid tissues, including the distal convoluted tubule of the kidney, chondrocytes and epididymis.
  • DOMAIN: The di-leucine motif is required for basolateral targeting in epithelial cells, and for targeting to matrix vesicles derived from mineralizing cells (By similarity).
  • PTM: Autophosphorylated as part of the catalytic cycle of phosphodiesterase/pyrophosphatase activity.
  • PTM: N-glycosylated.
  • PTM: It has been suggested that the active SMB domain may be permitted considerable disulfide bond heterogeneity or variability, thus two alternate disulfide patterns based on 3D structures are described with 1 disulfide bond conserved in both.
  • DISEASE: Defects in ENPP1 are a cause of increased susceptibility for ossification of the posterior longitudinal ligament of the spine (OPLL) [MIM:602475]. OPLL is a common form of human myelopathy with a prevalence of as much as 4% in a variety of ethnic groups.
  • DISEASE: Defects in ENPP1 are a cause of idiopathic infantile arterial calcification (IIAC) [MIM:208000]; also called generalized arterial calcification of infancy. IIAC is characterized by calcification of the internal elastic lamina of muscular arteries and stenosis due to myointimal proliferation.
  • DISEASE: Defects in ENPP1 are associated with obesity, glucose intolerance, and type II diabetes non-insulin dependent (NIDDM) [MIM:125853].
  • SIMILARITY: Belongs to the nucleotide pyrophosphatase/phosphodiesterase family.
  • SIMILARITY: Contains 2 SMB (somatomedin-B) domains.
  • CAUTION: It is uncertain whether Met-1 or Met-53 is the initiator.
