Automated description from the Alliance of Genome Resources (Release 7.0.0)
Enables ionotropic glutamate receptor binding activity and scaffold protein binding activity. Involved in several processes, including dendritic spine morphogenesis; locomotory exploration behavior; and neurotransmitter receptor localization to postsynaptic specialization membrane. Acts upstream of or within protein localization to synapse; regulation of long-term neuronal synaptic plasticity; and synaptic vesicle maturation. Located in several cellular components, including axon; postsynaptic density membrane; and synaptic vesicle. Part of AMPA glutamate receptor complex. Colocalizes with postsynaptic membrane. Is expressed in central nervous system; dorsal root ganglion; and sensory organ. Used to study Williams-Beuren syndrome and autism spectrum disorder. Human ortholog(s) of this gene implicated in autosomal dominant intellectual developmental disorder. Orthologous to human DLG4 (discs large MAGUK scaffold protein 4).
