Authors R Dingledine 1 , K Borges, D Bowie, S F Traynelis. Affiliation 1 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. 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. Ionotropic glutamate receptors (iGluRs) form the ion channel pore that activates when glutamate binds to the receptor.

The cloning of cDNAs encoding glutamate receptor subunits, which occurred mainly between 1989 and 1992 ([Hollmann and Heinemann, 1994][1]), stimulated this Glutamate receptor ion channels mediate excitatory responses at the majority of CNS synapses. They are the only ligand-gated ion channels for which multiple high-resolution crystal structures have been solved. Highlights of information gained from mechanistic studies based on the crystal structures of their Ionotropic glutamate receptors are integral mem-brane proteins composed of four large subunits ( 900 residues) that form a central ion channel pore.

Similar to other ligand-gated ion channels, their gating cycle begins with transitions from a ligand-free closed state to gluta-mate-bound active and desensitized states. Ionotropic glutamate receptors form ion channels, and conduct Na + and K + fluxes. The receptors possess an agonist binding site and it encounters a conformational change upon agonist binding to it.
