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. Belongs to the glutamate-gated ion channel (TC 1.A.10.1) family. GRIK1 subfamily. Most abundant in the cerebellum and the suprachiasmatic nuclei (SCN) of the hypothalamus. 2 alternatively spliced human isoforms have been reported.
