CC -!- FUNCTION: Receptor for glutamate that functions as a ligand-gated ion
CC channel in the central nervous system and plays an important role in
CC excitatory synaptic transmission. L-glutamate acts as an excitatory
CC neurotransmitter at many synapses in the central nervous system.
CC {ECO:0000256|RuleBase:RU367118}.
CC -!- SUBCELLULAR LOCATION: Cell membrane {ECO:0000256|RuleBase:RU367118};
CC Multi-pass membrane protein {ECO:0000256|RuleBase:RU367118}.
CC Postsynaptic cell membrane {ECO:0000256|RuleBase:RU367118}. Membrane
CC {ECO:0000256|ARBA:ARBA00004141}; Multi-pass membrane protein
CC {ECO:0000256|ARBA:ARBA00004141}.
CC -!- SIMILARITY: Belongs to the glutamate-gated ion channel (TC 1.A.10.1)
CC family. GRIK2 subfamily. {ECO:0000256|ARBA:ARBA00038119}.
