Gene Information

rat ... Dlg4(29495)

General description

DLG4 (discs large MAGUK scaffold protein 4) gene codes for the postsynaptic density-95 (PSD95) protein. Postsynaptic density 95 (PSD-95), a synaptic scaffolding protein is also a membrane-associated guanylate kinase (MAGUK) family protein. It has three PDZ domains on the N terminus followed by a Src homology 3 (SH3) domain and a guanylate kinase (GK) domain. This gene is located on human chromosome 17p13.1.


Reacts with both the recombinant and native rat PSD95. By immunofluorescence with rat hippocampal cells, a staining pattern coincident with NMDA receptor staining at synaptic sites consistent with its proposed role in receptor clustering is observed. Fixation with cold methanol is recommended.

Biochem/physiol Actions

Postsynaptic density 95 (PSD-95) plays a major role in bidirectional synaptic plasticity, an important process, essential for learning and memory. It exhibits increased dynamics upon induction of plasticity.
