| Metabotropic Glutamate Receptor 3 | |
|---|---|
| Protein Name | mGluR3 |
| Gene | GRM3 |
| UniProt ID | Q14832 |
| PDB Structures | 5CNK, 5CGF |
| Molecular Weight | ~95 kDa |
| Subcellular Localization | Plasma membrane (pre- and postsynaptic) |
| Protein Family | Class C G protein-coupled receptor (GPCR) |
mGluR3 shares the overall class C GPCR architecture with mGluR2, including the extracellular VFT domain, cysteine-rich domain, and seven-transmembrane domain. It can form heterodimers with mGluR2. The receptor has distinct pharmacological properties from mGluR2 despite high sequence similarity.
mGluR3 is expressed both presynaptically and postsynaptically. As a presynaptic receptor, it negatively modulates glutamate release. Postsynaptically, it modulates ion channel function and intracellular signaling. mGluR3 plays important roles in synaptic plasticity, cognition, and emotional regulation. It also regulates GABA release and is expressed in glial cells where it may modulate glutamate uptake.
| Disease | Role | Mechanism |
|---|---|---|
| Schizophrenia | Risk factor | Altered glutamate signaling affects cognition |
| Bipolar Disorder | Risk factor | Mood regulation |
| Alzheimer's Disease | Risk factor | Synaptic plasticity |
