| + | [https://www.uniprot.org/uniprot/GRIK2_RAT GRIK2_RAT] 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).<ref>PMID:17486098</ref> <ref>PMID:17115050</ref> | ||

| + | Incorporation of the azobenzene derivative gluazo, a synthetic photochromic ligand, into a kainate receptor allows for the optical control of neuronal activity. The crystal structure of gluazo bound to a dimeric GluK2 ligand-binding domain reveals one monomer in a closed conformation, occupied by gluazo, and the other in an open conformation, with a bound buffer molecule. The glutamate group of gluazo interacts like the natural glutamate ligand, while its trans-azobenzene moiety protrudes into a tunnel. This elongated cavity presumably cannot accommodate a cis-azobenzene, which explains the reversible activation of the receptor upon photoisomerization. | ||
