mGluR2 is a class C GPCR with a large extracellular venus flytrap (VFT) domain, a cysteine-rich domain (CRD), and a seven-transmembrane domain (7TM). The receptor forms homodimers. The VFT binds glutamate and other agonists, leading to conformational changes that are transmitted through the CRD to the 7TM domain, activating downstream signaling pathways.
mGluR2 is a presynaptic metabotropic glutamate receptor that negatively modulates glutamatergic neurotransmission. When activated by glutamate, it inhibits adenylyl cyclase, reduces cAMP production, and decreases neurotransmitter release. This feedback mechanism prevents excessive glutamate excitation. mGluR2 is involved in synaptic plasticity, learning, memory, and regulation of anxiety.
| Disease | Role | Mechanism |

| Schizophrenia | Risk factor | Altered glutamatergic transmission affects cortical function |
| Alzheimer's Disease | Risk factor | Synaptic dysfunction, impaired plasticity |
| Parkinson's Disease | Risk factor | Motor circuit dysregulation |
| Epilepsy | Risk factor | Excitotoxicity modulation |
