:Autotaxin (ATX) is a secreted enzyme that produces lysophosphatidic acid (LPA), which in turn activates GPCRs to elicit cellular responses. The crystal structures of mouse ATX in its apo state and bound to different LPAs and functional work reveal a hydrophobic tunnel that could participate in direct delivery of the product to its cognate GPCRs.
