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 PubMedFragment screening of a thermostabilized mGlu5 receptor using a high-concentration radioligand binding assay enabled the identification of moderate affinity, high ligand efficiency (LE) pyrimidine hit 5. Subsequent optimization using structure-based drug discovery methods led to the selection of 22, HTL14242, as an advanced lead compound for further development. Structures of the stabilized mGlu5 receptor complexed with 22 and another molecule in the series, 11, were determined at resolutions of 2.6A and 3.1A respectively.
