Summaries for GRID2 Gene

Entrez Gene Summary for GRID2 Gene

  • The protein encoded by this gene is a member of the family of ionotropic glutamate receptors which are the predominant excitatory neurotransmitter receptors in the mammalian brain. The encoded protein is a multi-pass membrane protein that is expressed selectively in cerebellar Purkinje cells. A point mutation in the mouse ortholog, associated with the phenotype named 'lurcher', in the heterozygous state leads to ataxia resulting from selective, cell-autonomous apoptosis of cerebellar Purkinje cells during postnatal development. Mice homozygous for this mutation die shortly after birth from massive loss of mid- and hindbrain neurons during late embryogenesis. This protein also plays a role in synapse organization between parallel fibers and Purkinje cells. Alternate splicing results in multiple transcript variants encoding distinct isoforms. Mutations in this gene cause cerebellar ataxia in humans. [provided by RefSeq, Apr 2014]

GeneCards Summary for GRID2 Gene

GRID2 (Glutamate Ionotropic Receptor Delta Type Subunit 2) is a Protein Coding gene. Diseases associated with GRID2 include Spinocerebellar Ataxia, Autosomal Recessive 18 and Depression. Among its related pathways are CREB Pathway and Peptide ligand-binding receptors. Gene Ontology (GO) annotations related to this gene include PDZ domain binding and ionotropic glutamate receptor activity. An important paralog of this gene is GRID1.

UniProtKB/Swiss-Prot for GRID2 Gene

  • 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. Promotes synaptogenesis and mediates the D-Serine-dependent long term depression signals and AMPA receptor endocytosis of cerebellar parallel fiber-Purkinje cell (PF-PC) synapses through the beta-NRX1-CBLN1-GRID2 triad complex (PubMed:27418511).

  • Spinocerebellar ataxia, autosomal recessive, 18 (SCAR18) [MIM:616204]: Spinocerebellar ataxia defines a clinically and genetically heterogeneous group of cerebellar disorders. Patients show progressive incoordination of gait and often poor coordination of hands, speech and eye movements, due to degeneration of the cerebellum with variable involvement of the brainstem and spinal cord. SCAR18 features include progressive cerebellar atrophy, delayed psychomotor development, severely impaired gait, ocular movement abnormalities, and intellectual disability. {ECO:0000269 PubMed:23611888, ECO:0000269 PubMed:24078737, ECO:0000269 PubMed:25841024, ECO:0000269 PubMed:27418511}. Note=The disease is caused by mutations affecting the gene represented in this entry.
