Summaries for GRIK5 Gene

Entrez Gene Summary for GRIK5 Gene

  • 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. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Jul 2014]

GeneCards Summary for GRIK5 Gene

GRIK5 (Glutamate Ionotropic Receptor Kainate Type Subunit 5) is a Protein Coding gene. Diseases associated with GRIK5 include Schizophrenia. Among its related pathways are Transmission across Chemical Synapses and Presynaptic function of Kainate receptors. Gene Ontology (GO) annotations related to this gene include identical protein binding and PDZ domain binding. An important paralog of this gene is GRIK4.

UniProtKB/Swiss-Prot for GRIK5 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. This receptor binds kainate > quisqualate > domoate > L-glutamate >> AMPA >> NMDA = 1S,3R-ACPD.

Tocris Summary for GRIK5 Gene

  • 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.
