Dlg4 - discs large MAGUK scaffold protein 4

Enables several functions, including PDZ domain binding activity; enzyme binding activity; and signaling receptor binding activity. A structural constituent of postsynaptic density. Involved in several processes, including modulation of chemical synaptic transmission; positive regulation of cellular component organization; and postsynapse organization. Located in several cellular components, including dendrite; juxtaparanode region of axon; and postsynaptic density. Is active in glutamatergic synapse. Is anchored component of postsynaptic density membrane. Colocalizes with postsynaptic membrane. Biomarker of Parkinson's disease and temporal lobe epilepsy. Human ortholog(s) of this gene implicated in autosomal dominant non-syndromic intellectual disability. Orthologous to human DLG4 (discs large MAGUK scaffold protein 4).
