Summary: This gene encodes a multi-pass transmembrane protein that forms a homotetramer or heterotetramer in neuronal cells. The encoded protein is a ligand-gated ion channel that responds to the neurotransmitter L-glutamate to promote synaptic transmission. Deficiency of this gene leads to behavioral phenotypes. The transcript is subject to RNA editing at codon 769 (AGA->GGA; R->G). Alternative splicing results in multiple transcript variants. [provided by RefSeq, Aug 2013]
Expression: Biased expression in frontal lobe adult (RPKM 31.4), cortex adult (RPKM 28.9) and 7 other tissues See more

Hippocampal AMPA receptor assemblies and mechanism of allosteric inhibition.
Title: Hippocampal AMPA receptor assemblies and mechanism of allosteric inhibition.
The central distribution of AMPARs is absent in GluA3-knockout mice, and gold particles are evenly distributed along the postsynaptic density. GluA4 gold labeling was homogenously distributed along both synapse types. Thus, GluA3 and GluA4 subunits are distributed at auditory nerve synapses in a target-cell-dependent manner.
Title: The number and distribution of AMPA receptor channels containing fast kinetic GluA3 and GluA4 subunits at auditory nerve synapses depend on the target cells.
The experiments reveal a novel type of plasticity at CA1 hippocampal synapses that is expressed by the activation of GluA3-containing AMPARs.

Results suggest a role for GluA3 channel activity in the regulation of sleep behavior in both mice and humans.
Title: A point mutation in the ion conduction pore of AMPA receptor GRIA3 causes dramatically perturbed sleep patterns as well as intellectual disability.
GluA3 is required for normal auditory signaling, normal ultrastructure of AN-BC synapses in the cochlear nucleus and normal experience-dependent changes in auditory processing after transient sound reduction.
Title: Impaired auditory processing and altered structure of the endbulb of Held synapse in mice lacking the GluA3 subunit of AMPA receptors.
These experiments indicate that the presence of GluA3-containing AMPARs is critical for Abeta-mediated synaptic and cognitive deficits.
Title: Amyloid-β effects on synapses and memory require AMPA receptor subunit GluA3.
Cerebellar learning depends on expression of GluA3 in Purkinje cells. GluA3 is required to induce long term potentiation (LTP), but not long term depression, at parallel fiber-Purkinje cell synapses. GluA3-dependent potentiation involves a cAMP-driven change in channel conductance. GluA3-mediated LTP and learning are induced via cAMP-mediated Epac activation.

These results provide direct evidence for cortical AMPA receptors to contribute to zymosan-induced visceral and spontaneous pain.
Title: Long-term upregulation of cortical glutamatergic AMPA receptors in a mouse model of chronic visceral pain.
Data indicate that the AMPA receptor subunits abundance is hippocampus, GluA2 > GluA1 > GluA3 >> GluA4; cortex, GluA2 > GluA3 >/= GluA1 >> GluA4; and cerebellum, GluA2 > GluA3 >/= GluA1 > GluA4.

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.

NR_104053.2 RNA Sequence

Status: REVIEWED

Description

Transcript Variant: This variant (3) contains an alternate internal exon, compared to variant 1. This variant is represented as non-coding because the use of the 5'-most expected translational start codon, as used in variant 1, renders the transcript a candidate for nonsense-mediated mRNA decay (NMD).
