Alternate Names
  • Glutamate receptor 2

  • GluR-B
  • GluR-K2
  • Glutamate receptor ionotropic, AMPA 2
  • GluA2
Background InformationGlutamate 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. Ser880 has been identified as the protein kinase C (PKC) phosphorylation site within the C-terminal region of GluR2 and has been shown to differentially regulate the interaction of the PDZ domain-containing proteins GRIP1 and PICK 1. In addition, PKC phosphorylation of GluR2 Ser880 appears to be a critical event in the induction of cerebellar long term depression (LTD).

Entrez Gene Number
Entrez Gene SummaryGlutamate 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 Number
UniProt SummaryFUNCTION: 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.

SUBUNIT STRUCTURE: 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. Interacts with PICK1 (via PDZ domain) (By similarity). Interacts with GRIA1 and TMEM90B (By similarity). Interacts with LRFN1.

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.

DEVELOPMENTAL STAGE: Detected at low levels in newborns. Levels increase strongly and are highest in hippocampus from 8 to 14 day old animals. Detected at intermediate levels at day 42 (at protein level).

PTM: Palmitoylated. Depalmitoylated upon glutamate stimulation. Cys-610 palmitoylation leads to Golgi retention and decreased cell surface expression. In contrast, Cys-836 palmitoylation does not affect cell surface expression but regulates stimulation-dependent endocytosis (By similarity).

MISCELLANEOUS: The postsynaptic actions of Glu are mediated by a variety of receptors that are named according to their selective agonists. This receptor binds AMPA (quisqualate) > glutamate > kainate.

SEQUENCE SIMILARITIES: Belongs to the glutamate-gated ion channel (TC 1.A.10.1) family. GRIA2 subfamily. [View classification]

RNA EDITING: Edited at position 607.

Fully edited in the brain. Heteromerically expressed edited GLUR2 (R) receptor complexes are impermeable to calcium, whereas the unedited (Q) forms are highly permeable to divalent ions (By similarity).
