Protein

Glutamate receptor ionotropic, kainate 2

Gene

Grik2

Organism
Rattus norvegicus (Rat)
Status
Reviewed-Annotation score: Annotation score: 5 out of 5-Experimental evidence at protein leveli

Functioni

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. May be involved in the transmission of light information from the retina to the hypothalamus. Modulates cell surface expression of NETO2 (By similarity).By similarity2 Publications

Interactioni

Subunit structurei

Homotetramer or heterotetramer of pore-forming glutamate receptor subunits. Tetramers may be formed by the dimerization of dimers. Assembles into a kainate-gated homomeric channel that does not bind AMPA (By similarity). GRIK2 associated to GRIK5 forms functional channels that can be gated by AMPA. Interacts with DLG4. Interacts with NETO2. Interacts (via C-terminus) with KLHL17 (via kelch repeats); the interaction targets GRIK2 for degradation via ubiquitin-proteasome pathway.By similarity6 Publications

Edited at positions 567, 571 and 621.1 Publication
Partially edited. The presence of Gln at position 621 (non-edited) determines channels with low calcium permeability, whereas an arginine residue (edited) determines a higher calcium permeability especially if the preceding sites are fully edited. This receptor is nearly completely edited in all gray matter structures (90% of the receptors).

Similar proteinsi

Links to similar proteins from the UniProt Reference Clusters (UniRef) at 100%, 90% and 50% sequence identity:
100%UniRef100 combines identical sequences and sub-fragments with 11 or more residues from any organism into one UniRef entry.
90%UniRef90 is built by clustering UniRef100 sequences that have at least 90% sequence identity to, and 80% overlap with, the longest sequence (a.k.a seed sequence).
50%UniRef50 is built by clustering UniRef90 seed sequences that have at least 50% sequence identity to, and 80% overlap with, the longest sequence in the cluster.
