Monoamine Transporters as Ionotropic Receptors

WebThe metabotropic glutamate receptors (mGluRs) are family C G-protein-coupled receptors that participate in the modulation of synaptic transmission and neuronal excitability throughout the central nervous system. The mGluRs bind glutamate within a large extracellular domain and transmit signals throu … WebSome metabotropic receptors have excitatory effects when they're activated (make the cell more likely to fire an action potential), while others have inhibitory effects. Often, these effects occur because the metabotropic receptor triggers a signaling pathway that opens or closes an ion channel.
