A model for lipid agonist binding generated through molecular modeling was used to dock two of the cannabinoid receptor CB<sub>1</sub>'s most abundant endogenous ligands into the LPA<sub>1</sub> binding pocket. <ref name="regpeps">PMID: 26091040</ref> Rotameric shifts of Trp210 and Trp271 leading to expansion of the binding pocket and the exposure of the π clouds of their indole rings provided favorable interactions with the double bonds of the phosphorylated cannabinoid ligands. This favorable binding provides evidence that the hydrophobic binding pockets of LPA<sub>1</sub> and CB<sub>1</sub> are able to favorably bind the same poly-unsaturated acyl chains with metabolically interconvertible head groups. <ref name="regpeps">PMID: 26091040</ref>

[[Image:TrpRotamericShiftsCM.png|200 px|left|thumb|Figure 1: Electrostatic illustration of the amphipathic binding pocket of the LPA<sub>1</sub> receptor. This binding pocket, located in the interior of the protein, has both polar and nonpolar regions. The blue and red coloration highlight the positively and negatively charged regions, respectively, and the white color shows the nonpolar region of the binding pocket.]]
