Ionotropic glutamate receptor that features to be a cation permeable ligand-gated ion channel, gated by L-glutamate as well as glutamatergic agonist kainic acid. L-glutamate acts being an excitatory neurotransmitter at many synapses from the central anxious process. Binding on the excitatory neurotransmitter L-glutamate induces a conformation adjus
