CC -!- FUNCTION: Receptor for glutamate. L-glutamate acts as an excitatory CC neurotransmitter at many synapses in the central nervous system. The CC postsynaptic actions of Glu are mediated by a variety of receptors that CC are named according to their selective agonists (By similarity). Forms CC ligand-gated ion channels which are activated by kainate. {ECO:0000250, CC ECO:0000269|PubMed:1359540}. CC -!- SUBUNIT: Homooligomer. {ECO:0000250}. CC -!- SUBCELLULAR LOCATION: Cell membrane {ECO:0000269|PubMed:1359540}; CC Multi-pass membrane protein {ECO:0000269|PubMed:1359540}. Cell CC junction, synapse, postsynaptic cell membrane {ECO:0000250}; Multi-pass CC membrane protein {ECO:0000250}. CC -!- ALTERNATIVE PRODUCTS: CC Event=Alternative splicing; Named isoforms=2; CC Name=1; Synonyms=A; CC IsoId=Q03445-1; Sequence=Displayed; CC Name=2; CC IsoId=Q03445-2; Sequence=VSP_014219; CC -!- TISSUE SPECIFICITY: Central nervous system. CC {ECO:0000269|PubMed:1359540}. CC -!- DEVELOPMENTAL STAGE: No expression is seen in early embryogenesis, CC whereas high expression occurs in late embryos. During larval CC development, expression decreases to undetectable levels in late CC larvae, resumes at the early pupal stage and gradually increases in CC late pupae and early adult flies. High levels of expression coincide CC with major stages of neurogenesis. {ECO:0000269|PubMed:1359540}. CC -!- SIMILARITY: Belongs to the glutamate-gated ion channel (TC 1.A.10.1) CC family. {ECO:0000305}.
