| additional information | Mus musculus | MAGUKs contain three PSD-95/Discs large/Zona occludens 1, i.e. PDZ, domains, an src-homology 3, i.e. SH3, domain and a C-terminal guanylate kinase domain and play a key role in the regulation of the intracellular trafficking and synaptic localization of ionotropic glutamate receptors. In particular, the postsynaptic density-95-like subfamily of MAGUKs, PSD-MAGUKs, organizes ionotropic glutamate receptors and their associated signaling proteins in the postsynaptic density of the excitatory synapse regulating the strength of synaptic activity. Alterations of PSD-MAGUK protein interaction with N-methyl-D-aspartate, NMDA, receptors regulatory subunits are common events in several CNS disorders, overview, NMDA receptors' synaptic localization and binding to PSD-MAGUK protein family play a key role in the control of downstream signals resulting from receptor activation, physiological function, overview | ? | - |
