Five of these ion channel receptor families have been shown to form a sequence-related superfamily: * Nicotinic acetylcholine receptor (AchR), an excitatory cation channel in vertebrates and invertebrates; in vertebrate motor endplates it is composed of alpha, beta, gamma and delta/epsilon subunits; in neurons it is composed of alpha and non-alpha (or beta) subunits Component of NMDA receptor complexes that function as heterotetrameric, ligand-gated ion channels with high calcium permeability and voltage-dependent sensitivity to magnesium. Channel activation requires binding of the neurotransmitter glutamate to the epsilon subunit, glycine binding to the zeta subunit, plus membrane depolarization to eliminate channel inhibition by Mg(2+).

Ionotropic glutamate receptors belong to the superfamily of P-loop channels as well as K ,Na , and Ca2 channels. However, the structural similarity between ion channels of the glutamate receptors and K channels is a matter of discussion. The aim of this study was to analyze differences between the structures of K channels and glutamate receptor

Ionotropic glutamate receptors are integral mem-brane proteins composed of four large subunits ( 900 residues) that form a central ion channel pore. Sequence similarity among all known glutamate receptor sub-units, including the AMPA,1 kainate, NMDA, and re-1Abbreviations: 5,7-DCKA, 5,7-dichlorokynurenic acid; AMPA, Ionotropic glutamate receptors (iGluRs) are tetrameric ion channels that mediate signal transmission at neuronal synapses, where they contribute centrally to the postsynaptic plasticity that underlies learning and memory. 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.
