We report the cryo-electron microscopy structures of fully inactive and intermediate-active conformations of mGlu receptor bound to an antagonist and a NAM or an agonist and a PAM, respectively, as well as the crystal structure of the 7TM bound to a photoswitchable NAM. The agonist induces a large movement between the subunits, bringing the 7TMs together and stabilizing a 7TM conformation structurally similar to the inactive state. Using functional approaches, we demonstrate that the PAM stabilizes a 7TM active conformation independent of the conformational changes induced by agonists, representing an alternative mode of mGlu activation. These findings provide a structural basis for different mGluR activation modes. | |||||||||

The Uniprot ID of mGluR5 is P41594 and the T4 lysozyme if P00720. The lysozyme sequence is inserted between residue 678 and 679 of mGluR5. In the PDB, the lysozyme is numbered from 1002-1162 (Asn & Tyr). The gaps are between 680-688 and 721-728. Residues 644 & 733 form a disuphide bond. The lysozyme has also been engineered and has the following mutations. C54T (in PDB it is 1054) and C97T (in PDB it is 1097). Source: (gene. exp.) Homo sapiens (human), (gene. exp.)
