CC -!- FUNCTION: Receptor for glutamate that functions as ligand-gated ion
CC channel in the central nervous system and plays an important role in
CC excitatory synaptic transmission. L-glutamate acts as an excitatory
CC neurotransmitter at many synapses in the central nervous system.
CC Binding of the excitatory neurotransmitter L-glutamate induces a
CC conformation change, leading to the opening of the cation channel, and
CC thereby converts the chemical signal to an electrical impulse. The
CC receptor then desensitizes rapidly and enters a transient inactive
CC state, characterized by the presence of bound agonist. In the presence
CC of CACNG4 or CACNG7 or CACNG8, shows resensitization which is
CC characterized by a delayed accumulation of current flux upon continued
CC application of glutamate (By similarity). {ECO:0000250}.
CC -!- SUBUNIT: Homotetramer or heterotetramer of pore-forming glutamate
CC receptor subunits. Tetramers may be formed by the dimerization of
CC dimers. Interacts with PRKCABP, GRIP1 and GRIP2 (By similarity). Found
CC in a complex with GRIA1, GRIA2, GRIA4, CNIH2, CNIH3, CACNG2, CACNG3,
CC CACNG4, CACNG5, CACNG7 and CACNG8. Interacts with CACNG5 (By
CC similarity). {ECO:0000250}.
CC -!- SUBCELLULAR LOCATION: Cell membrane {ECO:0000250}; Multi-pass membrane
CC protein {ECO:0000250}. Postsynaptic cell membrane {ECO:0000250}; Multi-
CC pass membrane protein {ECO:0000250}. Note=Interaction with CNIH2 and
CC CNIH3 promotes cell surface expression. {ECO:0000250}.
CC -!- DOMAIN: The M4 transmembrane segment mediates tetramerization and is
CC required for cell surface expression. {ECO:0000250}.
CC -!- PTM: Palmitoylated. Depalmitoylated upon glutamate stimulation. Cys-621
CC palmitoylation leads to Golgi retention and decreased cell surface
CC expression. In contrast, Cys-847 palmitoylation does not affect cell
CC surface expression but regulates stimulation-dependent endocytosis (By
CC similarity). {ECO:0000250}.
CC -!- MISCELLANEOUS: The postsynaptic actions of Glu are mediated by a
CC variety of receptors that are named according to their selective
CC agonists. This receptor binds AMPA (quisqualate) > glutamate > kainate.
CC -!- SIMILARITY: Belongs to the glutamate-gated ion channel (TC 1.A.10.1)
CC family. GRIA3 subfamily. {ECO:0000305}.
CC -!- CAUTION: It is uncertain whether Met-1 or Met-7 is the initiator.
CC {ECO:0000305}.
