Summary
Glutamate receptors are the predominant excitatory neurotransmitter receptors in the mammalian brain and are activated in a variety of normal neurophysiologic processes. These receptors are heteromeric protein complexes with multiple subunits, each possessing transmembrane regions, and all arranged to form a ligand-gated ion channel. The classification of glutamate receptors is based on their activation by different pharmacologic agonists. This gene belongs to a family of alpha-amino-3-hydroxy-5-methyl-4-isoxazole propionate (AMPA) receptors. Alternatively spliced transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Jul 2008]

NCBI Reference Sequences (RefSeq)

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.

    Status: REVIEWED

    Description
    Transcript Variant: This variant (6) has an alternate exon in place of the 5'-most exon of variant 1 and has an alternate in-frame exon in place of another exon of the same size. The resulting isoform (6) has a longer and distinct N-terminus and has a different sequence (but same length) segment in the C-terminus compared to isoform 1.

  1. NR_047578.1 RNA Sequence

    Status: REVIEWED

    Description
    Transcript Variant: This variant (8) lacks an alternate 5' exon and an alternate 3' exon compared to variant 1. The resulting transcript is a candidate for nonsense-mediated mRNA decay (NMD) and is therefore thought to be non-protein coding.
