function: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. This receptor binds domoate > kainate >> L-glutamate = quisqualate >> AMPA = NMDA.,RNA editing:Partially edited.,similarity:Belongs to the glutamate-gated ion channel (TC 1.A.10) family.,subunit:Homomeric. Can also coassemble with either GRIK4 or GRIK5 to form heteromeric receptors. Interacts with PRKCABP.,
