mGluR7 is a class C GPCR with the characteristic VFT, CRD, and 7TM domains. It has the highest affinity for glutamate among the mGluRs, making it a sensitive sensor of synaptic glutamate. The C-terminal tail is notably long and contains protein interaction domains that cluster the receptor at active zones.
mGluR7 is a presynaptic autoreceptor with the highest glutamate affinity among all mGluRs. It functions as a synaptic sensor, modulating neurotransmitter release at both glutamatergic and GABAergic synapses. The receptor is implicated in synaptic plasticity, anxiety, fear processing, and seizure susceptibility. It interacts with various synaptic proteins including PDZ domain proteins.

| Schizophrenia | Risk factor | Altered glutamatergic transmission |
| Major Depressive Disorder | Risk factor | Mood regulation |
| Autism Spectrum Disorder | Risk factor | Synaptic function |
| Epilepsy | Risk factor | Seizure threshold |
