Receptor for glutamate. L-glutamate acts as an excitatory neurotransmitter at many synapses in the central nervous system. The postsynaptic actions of Glu are mediated by a variety of receptors that are named according to their selective agonists (By similarity). This receptor binds domoate > kainate > AMPA > NBQX > glutamate. Homomeric. Belongs to the glutamate-gated ion channel (TC 1.A.10.1) family.
