Comments
  • 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.
  • 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.

    Q9EP80:Pick1; NbExp=6; IntAct=EBI-77718, EBI-77728;
  • 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.
  • ALTERNATIVE PRODUCTS: 3 named isoforms [FASTA] produced by alternative splicing.

    This is the isoform sequence displayed in this entry.
    NameFlip
    Isoform IDP19491-2
    Features which should be applied to build the isoform sequence: VSP_000111, VSP_000112, VSP_000113, VSP_000114.
    Name3
    SynonymsLong
    Isoform IDP19491-3
    Features which should be applied to build the isoform sequence: VSP_029310.
  • 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).
  • RNA EDITING: Modified_positions=607; Note=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).
  • 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.
  • SIMILARITY: Belongs to the glutamate-gated ion channel (TC 1.A.10) family [view classification].
