General annotation (Comments)

Function

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 By similarity.

Subunit structure

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. Ref.10

Subcellular location

Cell membrane; Multi-pass membrane protein By similarity. Cell junction › synapse › postsynaptic cell membrane; Multi-pass membrane protein By similarity. Note: Interaction with CNIH2 and CNIH3 promotes cell surface expression By similarity.

Post-translational modification

Palmitoylated. Depalmitoylated upon glutamate stimulation. Cys-615 palmitoylation leads to Golgi retention and decreased cell surface expression. In contrast, Cys-841 palmitoylation does not affect cell surface expression but regulates stimulation-dependent endocytosis By similarity. Ref.8

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. GRIA3 subfamily. [View classification]

Sequence caution

The sequence BAD90527.1 differs from that shown. Reason: Erroneous initiation. Translation N-terminally shortened.
