Key Ligand Interactions

Figure 3: Electrostatic illustration of the amphipathic binding pocket of the LPA1 receptor. This binding pocket was revealed by cutting away the exterior or the protein. 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.
