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. Promotes
CC synaptogenesis and mediates the D-Serine-dependent long term depression
CC signals and AMPA receptor endocytosis of cerebellar parallel fiber-
CC Purkinje cell (PF-PC) synapses through the beta-NRX1-CBLN1-GRID2 triad
CC complex (PubMed:27418511). {ECO:0000269|PubMed:27418511}.
CC -!- SUBUNIT: Tetramer; dimer of dimers (PubMed:27418511). Interacts with
CC EML2, MAGI2 (via PDZ domains) and AP4M1 (By similarity). Interacts with
CC BECN1, GOPC, GRID2IP, SHANK1 and SHANK2. Interacts with CBLN2, but not
CC with CBLN4 (By similarity). Interacts with CBLN1 (via C1q domain); the
CC interaction is CBLN1-NRX1 complex formation-dependent; CBLN1-binding is
CC calcium-independent; CBLN1 hexamers anchor GRID2 N-terminal domain
CC dimers to monomeric NRXN1 isoform beta; promotes synaptogenesis and
CC mediates the D-Serine-dependent long term depression signals and AMPA
CC receptor endocytosis (PubMed:27418511). {ECO:0000250|UniProtKB:Q61625,
CC ECO:0000250|UniProtKB:Q63226, ECO:0000269|PubMed:27418511}.
CC -!- SUBCELLULAR LOCATION: Cell membrane {ECO:0000250}; Multi-pass membrane
CC protein {ECO:0000250}. Postsynaptic cell membrane {ECO:0000250}; Multi-
CC pass membrane protein {ECO:0000250}.
CC -!- ALTERNATIVE PRODUCTS:
CC Event=Alternative splicing; Named isoforms=2;
CC Name=1;
CC IsoId=O43424-1; Sequence=Displayed;
CC Name=2;
CC IsoId=O43424-2; Sequence=VSP_054704;
CC -!- DOMAIN: The PDZ-binding motif mediates interaction with GOPC.
CC {ECO:0000250}.
CC -!- DISEASE: Spinocerebellar ataxia, autosomal recessive, 18 (SCAR18)
CC [MIM:616204]: A form of spinocerebellar ataxia, a clinically and
CC genetically heterogeneous group of cerebellar disorders. Patients show
CC progressive incoordination of gait and often poor coordination of
CC hands, speech and eye movements, due to degeneration of the cerebellum
CC with variable involvement of the brainstem and spinal cord. SCAR18
CC features include progressive cerebellar atrophy, delayed psychomotor
CC development, severely impaired gait, ocular movement abnormalities, and
CC intellectual disability. {ECO:0000269|PubMed:23611888,
CC ECO:0000269|PubMed:24078737, ECO:0000269|PubMed:25841024,
CC ECO:0000269|PubMed:27418511}. Note=The disease is caused by variants
CC affecting the gene represented in this entry.
CC -!- SIMILARITY: Belongs to the glutamate-gated ion channel (TC 1.A.10.1)
CC family. GRID2 subfamily. {ECO:0000305}.
CC -!- SEQUENCE CAUTION:
CC Sequence=BAD92555.1; Type=Erroneous initiation; Note=Extended N-terminus.; Evidence={ECO:0000305};
