| description | FUNCTION: Automated description from the Alliance of Genome Resources (Release 9.1.0) A structural constituent of postsynaptic density. Involved in several processes, including axo-dendritic protein transport; clustering of voltage-gated potassium channels; and neurotransmitter receptor localization to postsynaptic specialization membrane. Acts upstream of or within chemical synaptic transmission and sensory perception of pain. Located in several cellular components, including juxtaparanode region of axon; nucleus; and postsynaptic membrane. Is active in several cellular components, including axon initial segment; postsynaptic density; and synaptic vesicle membrane. Is expressed in jaw bone; nervous system; and retina. Orthologous to human DLG2 (discs large MAGUK scaffold protein 2). PHENOTYPE: Mice homozygous for a knock-out allele display lower surface expression of NMDA receptor (NMDAR) subunits NR2A and NR2B in dorsal horn neurons and significantly reduced NMDAR-mediated excitatory synaptic currents and NMDAR-dependent persistent inflammatory or nerve injury-induced neuropathic pain.
