Ionotropic glutamate receptor that capabilities like a cation permeable ligand-gated ion channel, gated by L-glutamate as well as the glutamatergic agonist kainic acid. L-glutamate acts being an excitatory neurotransmitter at many synapses during the central anxious process. Binding on the excitatory neurotransmitter L-glutamate induces a conformat
