[https://www.uniprot.org/uniprot/DLG4_RAT DLG4_RAT] Interacts with the cytoplasmic tail of NMDA receptor subunits and shaker-type potassium channels. Required for synaptic plasticity associated with NMDA receptor signaling. Overexpression or depletion of DLG4 changes the ratio of excitatory to inhibitory synapses in hippocampal neurons. May reduce the amplitude of ASIC3 acid-evoked currents by retaining the channel intracellularly. May regulate the intracellular trafficking of ADR1B.<ref>PMID:15317815</ref> <ref>PMID:15358863</ref>

== Publication Abstract from PubMed ==
 +
PSD-95/SAP90 is a member of the MAGUK superfamily. In excitatory synapses, PSD-95 clusters receptors and ion channels at specific sites in the postsynaptic membrane and organizes downstream signaling and cytoskeletal molecules. We have determined the crystal structures of the apo and GMP-bound forms to 2.3 and 2.0 A resolutions, respectively, of a fragment containing the SH3, HOOK, and guanylate kinase (GK) domains of PSD-95. We observe an intramolecular interaction between the SH3 and GK domains involving the formation of a beta sheet including residues N- and C-terminal to the GK domain. Based on amino acid conservation and mutational data available in the literature, we propose that this intramolecular interaction is a common feature among MAGUK proteins.
