Summary: Enables PDZ domain binding activity and scaffold protein binding activity. Involved in several processes, including cerebellar granule cell differentiation; heterophilic cell-cell adhesion via plasma membrane cell adhesion molecules; and regulation of postsynaptic density assembly. Acts upstream of or within several processes, including chemical synaptic transmission; prepulse inhibition; and regulation of neuron apoptotic process. Located in dendritic spine and postsynaptic membrane. Part of ionotropic glutamate receptor complex. Is active in glutamatergic synapse; parallel fiber to Purkinje cell synapse; and postsynaptic density membrane. Is expressed in several structures, including brain; eye; genitourinary system; intestine; and spinal cord. Used to study autosomal recessive spinocerebellar ataxia 18. Human ortholog(s) of this gene implicated in autosomal recessive spinocerebellar ataxia 18. Orthologous to human GRID2 (glutamate ionotropic receptor delta type subunit 2).

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
