Summary: Enables identical protein binding activity; kainate selective glutamate receptor activity; and protein domain specific binding activity. Involved in several processes, including cellular response to glucose stimulus; positive regulation of neuron apoptotic process; and protein retention in ER lumen. Located in several cellular components, including perikaryon; postsynaptic density; and terminal bouton. Part of ionotropic glutamate receptor complex. Is active in glutamatergic synapse. Is integral component of postsynaptic membrane and integral component of presynaptic membrane. Used to study visual epilepsy. Biomarker of temporal lobe epilepsy. Orthologous to human GRIK5 (glutamate ionotropic receptor kainate type subunit 5). [provided by Alliance of Genome Resources, Apr 2022]

What's a GeneRIF?

These findings indicate that ligand binding to only the GluK5 subunit is both necessary and sufficient to allow trafficking of recombinant GluK2/K5 heteromers to the cell membrane, but that occupancy of the GluK2 site alone is not.
Title: Agonist binding to the GluK5 subunit is sufficient for functional surface expression of heteromeric GluK2/GluK5 kainate receptors.
GluK2 and GluK5 assemble with 2:2 stoichiometry.
Title: Assembly stoichiometry of the GluK2/GluK5 kainate receptor complex.
CaMKII-dependent phosphorylation of GluK5 is responsible for synaptic depression by untrapping of KARs from the PSD and increased diffusion away from synaptic sites.
Title: CaMKII-dependent phosphorylation of GluK5 mediates plasticity of kainate receptors.
Heteromeric GluK2/K5 receptors expressed in human HEK-293T cells show markedly higher glutamate sensitivity than GluK2 homomers and do not desensitize at low glutamate concentrations.
Title: Distinct functional roles of subunits within the heteromeric kainate receptor.
kainic acid-preferring glutamate receptors are responsive to changes in plasma glucose concentrations and may participate in the activation of the paraventricular neurones during hypoglycaemic stress

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
