mGluR6 has the typical class C GPCR structure but is unique in its retinal expression and function. It forms homodimers and has an extended cysteine-rich domain. The receptor has distinctive pharmacology, being activated only by glutamate (not L-AP4 like other Group III mGluRs).
mGluR6 is exclusively expressed in retinal ON-bipolar cells, where it mediates the postsynaptic response to glutamate released from photoreceptors. When glutamate binds to mGluR6, it activates Go protein, closes cation channels, and hyperpolarizes the cell. This is essential for the ON pathway of visual signal transduction, converting light signals into neural signals.
| Disease | Role | Mechanism |

| Congenital Stationary Night Blindness | Pathogenic | ON-bipolar cell dysfunction |
| Visual Impairment | Pathogenic | Retinal signaling defects |
