Stereochemical structures of mGluR2/3 agonists, L-glutamic acid and LY354740 (A), and PAM (+)-TFMPIP (B). Schematic representation of an mGluR2/3 receptor (C) illustrating the extracellular N-terminal agonist binding domain connected to the transmembrane heptahelical domain. The extracellular portion of the heptihelical transmembrane domain contains the binding site for allosteric modulators.
