Ionotropic glutamate receptors (iGluRs) are ligand-gated cation channels that mediate neurotransmission in animal nervous systems. Homologous proteins in plants have been implicated in root

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.

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+).

Ion channel Ionotropic glutamate receptors are integral membrane proteins composed of four large subunits (>900 residues) that form a central ion channel pore.

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 (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. Ionotropic glutamate receptors are integral mem-brane proteins composed of four large subunits ( 900 residues) that form a central ion channel pore.

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 The ionotropic glutamate receptors are ligand-gated ion channels that mediate the vast majority of excitatory neurotransmission in the brain.

We report the characterization of two novel glutamate receptor subunits from recently sequenced ctenophore genomes. The origin of vertebrate NMDA subtype ionotropic glutamate receptors (iGluRs), which play a major role in synaptic plasticity and which require both glutamate and glycine for activation of ion channel gating, is not well understood.

Crystal structures are now available for the ligand-binding domain, but the structure of the ion channel itself remains unknown. The core of the ion channel shares structural features with an inverted K+ channel.
