Fig. 2

Binding pocket for ONO-0740556, viewed from the extracellular side (a) and membrane plane (b, c). ONO-0740556 and receptor residues involved in agonist binding are shown as orange and blue sticks, respectively. The dashed lines indicate hydrogen bonds. d Schematic representation of the interactions between ONO-0740556 and the receptor within 4.5 Å. e NanoBiT-G-protein dissociation assays for LPA1 and its mutants. Concentration–response curves for ONO-074055-dependent G-protein dissociation signals for LPA1 are shown as means ± s.e.m. from three independent experiments. To match the expression of LPA1-WT to those of mutants with lower expression, 1:5 volume [WT (1:5)] plasmid was used. Source data are provided as a Source Data file. It should be noted that mutations of these head phosphate group-recognizing residues enhanced the G-protein dissociation in high concentration of the agonist, while the reason is uncertain. f Conservation of the ONO-0740556 binding site in LPA1–6.
