FunctionFunction
Metabotropic glutamate receptors are glutamate receptors that activate ion channels indirectly through a signaling cascade involving G proteins[1]. They are members of the large class of seven-transmembrane domain receptors, the G protein-coupled receptors. Glutamate receptors are classified into 3 groups based on their homology, mechanism and pharmacological properties. See also Ligand Binding N-Terminal of Metabotropic Glutamate Receptors.
- Metabotropic glutamate receptor 1 and metabotropic glutamate receptor 5 belong to group I and activate phospholipase C.
- Metabotropic glutamate receptor 2 and metabotropic glutamate receptor 3 belong to group II and inhibit the cyclic AMP cascade.
- Metabotropic glutamate receptor 7 belongs to group III and inhibits adenylate cyclase activity.
