Ionotropic receptors, also called ligand-gated channels, are ion channels that are opened by the binding of neurotransmitters. Voltage-gated channels are opened by the membrane potential of the cell reaching threshold. Both types of channels allow ions to diffuse down their electrochemical gradient. The lined, teal channels represent glutamate Glutamate (Ionotropic) Receptors. NMDA, AMPA and Kainate receptors are members of the ionotropic class of glutamate receptors.

Authors. R Dingledine 1 , K Borges, D Bowie, S F Traynelis. Affiliation. 1Department of Pharmacology, Emory University School of Medicine, Atlanta, Georgia 30322, USA. rdingledine@pharm.emory.edu. The mammalian ionotropic glutamate receptor family encodes 18 gene products that coassemble to form ligand-gated ion channels containing an agonist recognition site, a transmembrane ion permeation pathway, and gating elements that couple agonist-induced conformational changes to the opening or closing of the permeation pore. 2005-06-01 · The glutamate receptor ion channels (iGluRs) are abundantly expressed in the brain and spinal cord and mediate responses at the vast majority of excitatory synapses. Mammalian iGluRs are encoded by 18 genes that assemble to form four major families, the AMPA, kainate, NMDA and delta receptors.

New insights into the structures of glutamate receptor ion channels (iGluRs), combined with functional and biochemical data, can help us to understand how agonist binding triggers their activation Ionotropic glutamate receptors (iGluRs) form the ion channel pore that activates when glutamate binds to the receptor. Metabotropic glutamate receptors (mGluRs) affect the cell through a signal transduction cascade, and they may be primarily activating (mGlur 1/5) or primarily inhibitory (mGlur 2/3 and mGlur 4/6/7/8). Ionotropic receptors tend to be quicker in relaying information, but metabotropic ones are associated with a more prolonged stimulus. The ionotropic glutamate receptors are ligand-gated ion channels that mediate the vast majority of excitatory neurotransmission in the brain.
