Grid2 Gene Summary [Rat]
Enables PDZ domain binding activity and identical protein binding activity. Involved in regulation of presynapse assembly. Located in postsynaptic membrane. Is active in glutamatergic synapse; parallel fiber to Purkinje cell synapse; and postsynaptic density membrane. Human ortholog(s) of this gene implicated in autosomal recessive spinocerebellar ataxia 18. Orthologous to human GRID2 (glutamate ionotropic receptor delta type subunit 2).
