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. Ref.12 Ref.17
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. Found in a complex with GRIA2, GRIA3, GRIA4, CNIH2, CNIH3, CACNG2, CACNG3, CACNG4, CACNG5, CACNG7 and CACNG8. Interacts with HIP1, RASGRF2, SYNDIG1 and LRFN1. Interacts with SNX27 (via PDZ domain); the interaction is required for recycling to the plasma membrane when endocytosed and prevent degradation in lysosomes. Interacts (via PDZ-binding motif) with SHANK3 (via PDZ domain). Ref.10 Ref.11 Ref.12 Ref.13 Ref.14 Ref.15 Ref.17 Ref.18 Ref.19 Ref.20
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. Cell junction › synapse › postsynaptic cell membrane › postsynaptic density By similarity. Cell projection › dendrite By similarity. Cell projection › dendritic spine By similarity. Note: Interaction with CACNG2, CNIH2 and CNIH3 promotes cell surface expression. Ref.11 Ref.12 Ref.17
Tissue specificity	Detected in cerebellum (at protein level). Ref.11
Domain	The M4 transmembrane segment mediates tetramerization and is required for cell surface expression By similarity.
Post-translational modification	Palmitoylated. Depalmitoylated upon glutamate stimulation. Cys-603 palmitoylation 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 By similarity.
Polymorphism	Both variants Ser-710 and Thr-710 are phosphorylated at this position.
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]
