Grid2 - glutamate receptor, ionotropic, delta 2

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 and parallel fiber to Purkinje cell synapse. Is integral component of 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). [provided by Alliance of Genome Resources, Apr 2022]
