LPA(1) is a drug target for various diseases, including cancer, inflammation, and neuropathic pain. Notably, LPA(1) agonists have potential therapeutic value for obesity and urinary incontinence. Here, we report a cryo-electron microscopy structure of the active human LPA(1)-G(i) complex bound to ONO-0740556, an LPA analog with more potent activity against LPA(1). Our structure elucidated the details of the agonist binding mode and receptor activation mechanism mediated by rearrangements of transmembrane segment 7 and the central hydrophobic core. A structural comparison of LPA(1) and other phylogenetically-related lipid-sensing GPCRs identified the structural determinants for lipid preference of LPA(1). Moreover, we characterized the structural polymorphisms at the receptor-G-protein interface, which potentially reflect the G-protein dissociation process. Our study provides insights into the detailed mechanism of LPA(1) binding to agonists and paves the way toward the design of drug-like agonists targeting LPA(1).
