| Background Information | Glutamate receptors (GluRs) can be categorized as ionotropic or metabotropic and subcatergorized by their agonist preferences (NMDA, AMPA or Kainic acid). There are four types of AMPA selective GluR subunits (GluR1, GluR2, GluR3 and GluR4). Tetrameric or pentameric combinations of different subunits contributes to the functional diversity of AMPA receptors. In general, AMPA receptors mediate fast synaptic current at most excitatory synapses, with stoichiometry characterized by subtype composition. Although subunit composition of AMPA receptors varies, they must contain at least one edited GluR2 subunit to be calcium impermeable. The critical residue controlling calcium permeability is in the pore loop region. In GluR1, GluR3, and GluR4, this positionis occupied by a Gln residue. In GluR2, it is occupied by an Arg residue. It has been shown experimentally that the presence of Arg in this position blocks CA2+ ion permeability, while a Gln does not. Relative calcium permeability in AMPA receptor channels may be significant in pathological neurotoxic damage and long term changes in nervous system responses. |

| Entrez Gene Number |
|
| Entrez Gene Summary | Glutamate receptors are the predominant excitatory neurotransmitter receptors in the mammalian brain and are activated in a variety of normal neurophysiologic processes. This gene product belongs to a family of glutamate receptors that are sensitive to alpha-amino-3-hydroxy-5-methyl-4-isoxazole propionate (AMPA), and function as ligand-activated cation channels. These channels are assembled from 4 related subunits, Gria1-4. The subunit encoded by this gene (Gria2) is subject to RNA editing (Q/R and R/G), which is thought to render the channels impermeable to Ca(2+), and to affect the kinetic aspects of these channels in rat brain. Alternative splicing, resulting in transcript variants encoding different isoforms (flip and flop), has been noted for this gene. [provided by RefSeq]. |

| UniProt Summary | FUNCTION: Ionotropic glutamate receptor. L-glutamate acts as an excitatory neurotransmitter at many synapses in the central nervous system. Binding of the excitatory neurotransmitter L-glutamate induces a conformation change, leading to the opening of the cation channel, and thereby converts the chemical signal to an electrical impulse. The receptor then desensitizes rapidly and enters a transient inactive state, characterized by the presence of bound agonist. SIZE: 883 amino acids; 98,688 Da SUBUNIT: Homotetramer or heterotetramer of pore-forming glutamate receptor subunits. Tetramers may be formed by the dimerization of dimers. May interact with MPP4. Forms a ternary complex with GRIP1 and CSPG4(By similarity). Interacts with CACNG2, PRKCABP, GRIP1 and GRIP2. Interacts with NSF via its C-terminus. Part of a complex containing GRIA2, NSF and NAPA and/or NAPB. SUBCELLULAR LOCATION: Cell membrane; Multi-pass membrane protein. Endoplasmic reticulum membrane; Multi-pass membrane protein. Cell junction › synapse › postsynaptic cell membrane; Multi-pass membrane protein. Note= Interaction with CACNG2 promotes cell surface expression. TISSUE SPECIFICITY: Detected in forebrain. Detected in dendrites of neuronal cells. SIMILARITY: Belongs to the glutamate-gated ion channel (TC 1.A.10) family. |
