Function	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 (By similarity). {ECO:0000250}.
Subcellular Location	Cell membrane {ECO:0000269|PubMed:12151521}; Peripheral membrane protein {ECO:0000269|PubMed:12151521}. Cell junction, synapse, postsynaptic cell membrane, postsynaptic density {ECO:0000269|PubMed:12151521}. Cell projection, axon {ECO:0000250|UniProtKB:P31016}. Cell junction, synapse {ECO:0000269|PubMed:12151521}. Note=High levels in postsynaptic density of neurons in the forebrain. Also in presynaptic region of inhibitory synapses formed by cerebellar basket cells on axon hillocks of Purkinje cells.
Tissue Specificity	Brain.
