nucleotide pyrophosphatase/phosphodiesterase family

DESCRIPTION

Also known as ENPP2_RAT, Enpp2, Atx, Npps2. Hydrolyzes lysophospholipids to produce the signaling molecule lysophosphatidic acid (LPA) in extracellular fluids (PubMed:12633853, PubMed:29259743, PubMed:27660691, PubMed:27268273, PubMed:27075612, PubMed:12354767). Major substrate is lysophosphatidylcholine (PubMed:12119361, PubMed:27660691, PubMed:27268273, PubMed:27075612, PubMed:12176993). Also can act on sphingosylphosphorylcholine producing sphingosine-1-phosphate, a modulator of cell motility (PubMed:12119361). Can hydrolyze, in vitro, bis-pNPP, to some extent pNP-TMP, and barely ATP (PubMed:12633853, PubMed:27268273). Involved in several motility-related processes such as angiogenesis and neurite outgrowth. Acts as an angiogenic factor by stimulating migration of smooth muscle cells and microtubule formation. Stimulates migration of melanoma cells, probably via a pertussis toxin-sensitive G protein. May have a role in induction of parturition. Possible involvement in cell proliferation and adipose tissue development. Tumor cell motility-stimulating factor (By similarity). Required for LPA production in activated platelets, cleaves the sn-1 lysophospholipids to generate sn-1 lysophosphatidic acids containing predominantly 18:2 and 20:4 fatty acids (By similarity). Shows a preference for the sn-1 to the sn-2 isomer of 1-O-alkyl-sn-glycero-3-phosphocholine (lyso-PAF) (By similarity).
