mGluR1

Metabotropic glutamate receptors (mGluRs) are G-protein coupled receptors activated by glutamate. Based on sequence similarity, transduction mechanisms and agonist potencies, mGluRs are subdivided into three groups: mGluR1/mGluR5, mGluR2/mGluR3, and mGluR4/mGluR6/mGluR7/mGluR8. mGluRs are widely distributed throughout the nervous system and are expressed by both neurons and glial cells

mGluR1 modulates excitatory and inhibitory synaptic transmission in various brain areas including the activation of glutamate-driven synaptic inhibition in the cerebellum. mGluR1 and other mGluRs have emerged as therapeutic targets for neuropsychiatric disorders associated with cortical dysfunction and the modulation of nociceptive and neuropathic pain.
