Function
[GRM5_HUMAN] Receptor for glutamate. The activity of this receptor is mediated by a G-protein that activates a phosphatidylinositol-calcium second messenger system and generates a calcium-activated chloride current.
Publication Abstract from PubMed
Metabotropic glutamate receptors are class C G-protein-coupled receptors which respond to the neurotransmitter glutamate. Structural studies have been restricted to the amino-terminal extracellular domain, providing little understanding of the membrane-spanning signal transduction domain. Metabotropic glutamate receptor 5 is of considerable interest as a drug target in the treatment of fragile X syndrome, autism, depression, anxiety, addiction and movement disorders. Here we report the crystal structure of the transmembrane domain of the human receptor in complex with the negative allosteric modulator, mavoglurant. The structure provides detailed insight into the architecture of the transmembrane domain of class C receptors including the precise location of the allosteric binding site within the transmembrane domain and key micro-switches which regulate receptor signalling. This structure also provides a model for all class C G-protein-coupled receptors and may aid in the design of new small-molecule drugs for the treatment of brain disorders.
