Expression of PSD95 enhances synaptic clustering of AMPA but not NMDA receptors
Over-expression of PSD95 increases the amplitude and frequency of AMPA receptor mEPSC
Recovery of NMDA receptor mediated EPSCs following MK801 block
Common element in three structurally related proteins: PSD95/SAP90 (Post-synaptic density protein 95/synapse associated protein 90) Dlg (Drosophila tumor suppressor gene discs-large) Zo-1 (Zona occludens-1)
