Summary: Enables kainate selective glutamate receptor activity and transmitter-gated ion channel activity involved in regulation of postsynaptic membrane potential. Acts upstream of or within excitatory postsynaptic potential; glutamatergic synaptic transmission; and regulation of synaptic vesicle fusion to presynaptic active zone membrane. Located in endoplasmic reticulum; postsynaptic membrane; and presynaptic membrane. Part of kainate selective glutamate receptor complex. Is active in hippocampal mossy fiber to CA3 synapse. Is integral component of postsynaptic density membrane and integral component of presynaptic membrane. Is expressed in several structures, including alimentary system; central nervous system; genitourinary system; immune system; and visual system. Orthologous to human GRIK5 (glutamate ionotropic receptor kainate type subunit 5). [provided by Alliance of Genome Resources, Apr 2022]

This study demonistrated that Grik5 gene expression in mouse dorsal raphe nucleus
Title: Patterned expression of ion channel genes in mouse dorsal raphe nucleus determined with the Allen Mouse Brain Atlas.
Postsynaptic and presynaptic mossy-fiber kainate receptor function is altered in neurons from KA2-/- mice; presynaptic facilitatory autoreceptor had a reduced affinity for exogenous agonists and synaptic glutamate
Title: Loss of kainate receptor-mediated heterosynaptic facilitation of mossy-fiber synapses in KA2-/- mice.
Trafficking motifs in both intracellular loop and C terminus regulate KA2 surface expression; however, in neurons, GluR6 oligomerization is required for egress of KA2 from endoplasmic reticulum and transport to cell surface.
Title: Identification of an endoplasmic reticulum-retention motif in an intracellular loop of the kainate receptor subunit KA2.
Association between COPI proteins and KA2 subunits was significantly reduced upon alanine substitution of this signal in the cytoplasmic tail of KA2.
Title: Intracellular trafficking of KA2 kainate receptors mediated by interactions with coatomer protein complex I (COPI) and 14-3-3 chaperone systems.

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.
