General annotation (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. 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 structure | Homotetramer or heterotetramer of pore-forming glutamate receptor subunits. Tetramers may be formed by the dimerization of dimers. Interacts with DLG1 via its C-terminus. Interacts with CACNG2 By similarity. Interacts with HIP1 and RASGRF2. Interacts with SYNDIG1 and GRIA2. Interacts with LRFN1 By similarity. Found in a complex with GRIA2, GRIA3, GRIA4, CNIH2, CNIH3, CACNG2, CACNG3, CACNG4, CACNG5, CACNG7 and CACNG8. Interacts with CNIH2, CACNG2 AND CACGN5 By similarity. Ref.2 Ref.4 Ref.5 |
| Subcellular location | Cell membrane; Multi-pass membrane protein. Endoplasmic reticulum membrane; Multi-pass membrane protein By similarity. Cell junction › synapse › postsynaptic cell membrane; Multi-pass membrane protein. Cell junction › synapse › postsynaptic cell membrane › postsynaptic density. Cell projection › dendrite. Cell projection › dendritic spine. Note: Interaction with CACNG2, CNIH2 and CNIH3 promotes cell surface expression By similarity. Ref.6 |
| Post-translational modification | Palmitoylated. Depalmitoylated upon glutamate stimulation. ZDHHC3/GODZ specifically palmitoylates Cys-603, which leads to Golgi retention and decreased cell surface expression. In contrast, Cys-829 palmitoylation does not affect cell surface expression but regulates stimulation-dependent endocytosis. Ref.3 |
| 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. GRIA1 subfamily. [View classification] |
