http://identifiers.org/unip...biopax3:commentFUNCTION: Receptor for glutamate that functions as ligand-gated ion channel in the central nervous system and plays an important role in excitatory synaptic transmission. 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.In the presence of CACNG4 or CACNG7 or CACNG8, shows resensitization which is characterized by a delayed accumulation of current flux upon continued application of glutamate. SUBUNIT: Homotetramer or heterotetramer of pore-forming glutamate receptor subunits. Tetramers may be formed by the dimerization of dimers. Interacts with PRKCABP, GRIP1 and GRIP2 (By similarity). Found in a complex with GRIA1, GRIA2, GRIA4, CNIH2, CNIH3, CACNG2, CACNG3, CACNG4, CACNG5, CACNG7 and CACNG8. Interacts with CACNG5 (By similarity). SUBCELLULAR LOCATION: Cell membrane; Multi-pass membrane protein. Cell junction, synapse, postsynaptic cell membrane; Multi-pass membrane protein. Note=Interaction with CNIH2 and CNIH3 promotes cell surface expression (By similarity). ALTERNATIVE PRODUCTS: Event=Alternative splicing; Named isoforms=2; Name=Flop; IsoId=P42263-1; Sequence=Displayed; Name=Flip; IsoId=P42263-2; Sequence=VSP_000115, VSP_000116, VSP_000117, VSP_000118; PTM: Palmitoylated. Depalmitoylated upon glutamate stimulation. Cys-621 palmitoylation leads to Golgi retention and decreased cell surface expression. In contrast, Cys-847 palmitoylation does not affect cell surface expression but regulates stimulation-dependent endocytosis (By similarity). DISEASE: Defects in GRIA3 are the cause of mental retardation X- linked type 94 (MRX94) [MIM:300699]. Mental retardation is characterized by significantly sub-average general intellectual functioning associated with impairments in adaptative behavior and manifested during the developmental period. MRX94 patients have moderate mental retardation. Other variable features are macrocephaly, seizures, myoclonic jerks, autistic behavior, asthenic body habitus, distal muscle weakness and hyporeflexia. 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.10.1) family. GRIA3 subfamily. CAUTION: It is uncertain whether Met-1 or Met-7 is the initiator. GENE SYNONYMS:GRIA3 GLUR3 GLURC. COPYRIGHT: Protein annotation is derived from the UniProt Consortium (http://www.uniprot.org/).
