Grik2 (P42260) - Overview - Molecular Target Synopsis


Grik2, Glutamate receptor ionotropic, kainate 2
UniProt P42260

Also Known as GRIK2_RAT, Grik2, Glur6

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 (PubMed:17115050, PubMed:17486098). May be involved in the transmission of light information from the retina to the hypothalamus. Modulates cell surface expression of NETO2. 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.
