[ | [https://www.uniprot.org/uniprot/ENPP2_MOUSE ENPP2_MOUSE] Hydrolyzes lysophospholipids to produce lysophosphatidic acid (LPA) in extracellular fluids. Major substrate is lysophosphatidylcholine. Also can act on sphingosylphosphphorylcholine producing sphingosine-1-phosphate, a modulator of cell motility. Can hydrolyze, in vitro, bis-pNPP, to some extent pNP-TMP, and barely ATP. 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.<ref>PMID:15700135</ref> <ref>PMID:17208043</ref> <ref>PMID:21240269</ref> | ||

== Publication Abstract from PubMed == | |||
ATX is a plasma lysophospholipase D that hydrolyzes lysophosphatidylcholine (LPC) and produces lysophosphatidic acid. To date, no ATX-inhibition-mediated treatment strategies for human diseases have been established. Here, we report anti-ATX DNA aptamers that inhibit ATX with high specificity and efficacy. We solved the crystal structure of ATX in complex with the anti-ATX aptamer RB011, at 2.0-A resolution. RB011 binds in the vicinity of the active site through base-specific interactions, thus preventing the access of the choline moiety of LPC substrates. Using the structural information, we developed the modified anti-ATX DNA aptamer RB014, which exhibited in vivo efficacy in a bleomycin-induced pulmonary fibrosis mouse model. Our findings reveal the structural basis for the specific inhibition of ATX by the anti-ATX aptamer and highlight the therapeutic potential of anti-ATX aptamers for the treatment of human diseases, such as pulmonary fibrosis. | |||
