|---|---|
| Protein Name | mGluR8 |
| Gene | GRM8 |

| Subcellular Localization | Plasma membrane (presynaptic) |
| Protein Family | Class C G protein-coupled receptor (GPCR) |
mGluR8 is a Group III metabotropic glutamate receptor with the typical class C GPCR architecture. It has high affinity for glutamate, similar to mGluR7. The receptor can form homodimers and interacts with various synaptic proteins.
mGluR8 is a presynaptic autoreceptor that regulates glutamate release. It has the highest affinity for glutamate among Group III mGluRs, making it a sensitive detector of synaptic glutamate levels. The receptor is widely expressed in brain, particularly in cortex, hippocampus, and basal ganglia. It plays roles in anxiety, fear processing, and seizure regulation.
| Disease | Role | Mechanism |

| Epilepsy | Risk factor | Seizure threshold modulation |
| Autism Spectrum Disorder | Risk factor | Synaptic modulation |
| Anxiety Disorders | Risk factor | Fear circuitry |
