Glutamate receptors are the predominant excitatory neurotransmitter receptors in the mammalian brain and are activated in a variety of normal neurophysiologic processes. This gene product belongs to the kainate family of glutamate receptors, which are composed of four subunits and function as ligand-activated ion channels. The subunit encoded by this gene is subject to RNA editing (CAG->CGG; Q->R) within the second transmembrane domain, which is thought to alter the properties of ion flow. Alternative splicing, resulting in transcript variants encoding different isoforms, has been noted for this gene. [provided by RefSeq, Jul 2008]
GeneCards Summary for GRIK1 Gene
GRIK1 (Glutamate Ionotropic Receptor Kainate Type Subunit 1) is a Protein Coding gene. Diseases associated with GRIK1 include Juvenile Absence Epilepsy and Monosomy 21. Among its related pathways are Circadian entrainment and Transmission across Chemical Synapses. Gene Ontology (GO) annotations related to this gene include ionotropic glutamate receptor activity and kainate selective glutamate receptor activity. An important paralog of this gene is GRIK2.
UniProtKB/Swiss-Prot Summary for GRIK1 Gene
Ionotropic glutamate receptor. 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. May be involved in the transmission of light information from the retina to the hypothalamus.
Kainate receptors are members of the ionotropic class of glutamate receptors, which also includes NMDA and AMPA receptors. Kainate receptors have been identified both pre- and post-synaptically. They contribute to excitatory postsynaptic currents in many regions of the CNS.
