Metabotropic glutamate receptor 2 (mGluR2) is a protein that, in humans, is encoded by the GRM2gene.[5][6] mGluR2 is a G protein-coupled receptor (GPCR) that couples with the Gi alpha subunit.[7] The receptor functions as an autoreceptor for glutamate, that upon activation, inhibits the emptying of vesicular contents at the presynaptic terminal of glutamatergic neurons.
