|Function||Receptor for glutamate that functions as ligand-gated ion channel in the central nervous system and plays an important role in excitatory synaptic transmission. L-glutamate acts as an excitatory neurotransmitter at many synapses in the central nervous system. Binding of the excitatory neurotransmitter L- glutamate induces a conformation change, leading to the opening of the cation channel, and thereby converts the chemical signal to an electrical impulse. The receptor then desensitizes rapidly and enters a transient inactive state, characterized by the presence of bound agonist. In the presence of CACNG4 or CACNG7 or CACNG8, shows resensitization which is characterized by a delayed accumulation of current flux upon continued application of glutamate.|

Glutamate receptors are the predominant excitatoryneurotransmitter receptors in the mammalian brain and are activatedin a variety of normal neurophysiologic processes. These receptorsare heteromeric protein complexes composed of multiple subunits,arranged to form ligand-gated ion channels. The classification ofglutamate receptors is based on their activation by differentpharmacologic agonists. The subunit encoded by this gene belongs toa family of AMPA (alpha-amino-3-hydroxy-5-methyl-4-isoxazolepropionate)-sensitive glutamate receptors, and is subject to RNAediting (AGA->GGA; R->G). Alternative splicing of this gene resultsin transcript variants encoding different isoforms, which may varyin their signal transduction properties. Some haplotypes of thisgene show a positive association with schizophrenia. [provided byRefSeq].
