This gene encodes a protein that belongs to the glutamate-gated ionic channel family. Glutamate functions as the major excitatory neurotransmitter in the central nervous system through activation of ligand-gated ion channels and G protein-coupled membrane receptors. The protein encoded by this gene forms functional heteromeric kainate-preferring ionic channels with the subunits encoded by related gene family members. Alternatively spliced transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Sep 2013]
GeneCards Summary for GRIK4 Gene
GRIK4 (Glutamate Ionotropic Receptor Kainate Type Subunit 4) is a Protein Coding gene. Diseases associated with GRIK4 include Bipolar Disorder and Megalencephalic Leukoencephalopathy With Subcortical Cysts 2B, Remitting, With Or Without Mental Retardation. Among its related pathways are Peptide ligand-binding receptors and Presynaptic function of Kainate receptors. 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 GRIK5.
UniProtKB/Swiss-Prot Summary for GRIK4 Gene
Receptor for glutamate. L-glutamate acts as an excitatory neurotransmitter at many synapses in the central nervous system. The postsynaptic actions of Glu are mediated by a variety of receptors that are named according to their selective agonists.
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.
