| Tissue Specificity | Expressed in brain (at protein level). Detected in juxtaparanodal zones in the central nervous system and at nerve terminal plexuses of basket cells in the cerebellum. Expressed in cerebrum. Expressed in hippocampal neurons (at protein level). Isoform 1 and isoform 2: highly expressed in cerebellum, cortex, hippocampus, and corpus striatum. |
| Post Translational Modifications | Palmitoylated. Palmitoylation is required for targeting to postsynaptic density, plasma membrane and synapses. Palmitoylation by ZDHHC2 occurs when the synaptic activity decreases and induces DLG4 synaptic clustering. Palmitoylation by ZDHHC15 regulates trafficking to the postsynaptic density and function in synaptogenesis. Palmitoylation may play a role in glutamate receptor GRIA1 synapse clustering. Depalmitoylated by ABHD17A and ABHD17B and to a lesser extent by ABHD17C, ABHD12, ABHD13, LYPLA1 and LYPLA2. Undergoes rapid synaptic palmitoylation/depalmitoylation cycle during neuronal development which slows down in mature neurons. Ubiquitinated by MDM2 in response to NMDA receptor activation, leading to proteasome-mediated degradation of DLG4 which is required for AMPA receptor endocytosis. |
| Function | Postsynaptic scaffolding protein that plays a critical role in synaptogenesis and synaptic plasticity by providing a platform for the postsynaptic clustering of crucial synaptic proteins. 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. Also regulates AMPA-type glutamate receptor (AMPAR) immobilization at postsynaptic density keeping the channels in an activated state in the presence of glutamate and preventing synaptic depression.Under basal conditions, cooperates with FYN to stabilize palmitoyltransferase ZDHHC5 at the synaptic membrane through FYN-mediated phosphorylation of ZDHHC5 and its subsequent inhibition of association with endocytic proteins. |
