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. May be involved in the transmission of light information from the retina to the hypothalamus. Modulates cell surface expression of NETO2. Belongs to the glutamate-gated ion channel (TC 1.A.10.1) family. GRIK2 subfamily. Expression is higher in cerebellum than in cerebral cortex. 7 alternatively spliced human isoforms have been reported. Note: This description may include information from UniProtKB.
