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. 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).

With optimized assays we ensure the provision of insightful, accurate data to drive your discovery programs.

For brains to develop and form memories, a signal must be transmitted from one neuron to the next. Glutamate is an important neurotransmitter that excites the receiving nerve cell by binding to an ion channel called an N-Methyl-d-Aspartate (NMDA) receptor. Component of NMDA receptor complexes that function as heterotetrameric, ligand-gated ion channels with high calcium permeability and voltage-dependent sensitivity to magnesium.

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. 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).
