CC -!- FUNCTION: Postsynaptic scaffolding protein that plays a critical role
CC in synaptogenesis and synaptic plasticity by providing a platform for
CC the postsynaptic clustering of crucial synaptic proteins
CC (PubMed:15317815, PubMed:15358863, PubMed:19596852, PubMed:23300088,
CC PubMed:26679993). Interacts with the cytoplasmic tail of NMDA receptor
CC subunits and shaker-type potassium channels. Required for synaptic
CC plasticity associated with NMDA receptor signaling. Overexpression or
CC depletion of DLG4 changes the ratio of excitatory to inhibitory
CC synapses in hippocampal neurons. May reduce the amplitude of ASIC3
CC acid-evoked currents by retaining the channel intracellularly. May
CC regulate the intracellular trafficking of ADR1B (By similarity). Also
CC regulates AMPA-type glutamate receptor (AMPAR) immobilization at
CC postsynaptic density keeping the channels in an activated state in the
CC presence of glutamate and preventing synaptic depression
CC (PubMed:19596852).Under basal conditions, cooperates with FYN to

CC occurs when the synaptic activity decreases and induces DLG4 synaptic

CC glutamate receptor GRIA1 synapse clustering (PubMed:27307232).

CC ABHD17C, ABHD12, ABHD13, LYPLA1 and LYPLA2 (PubMed:27307232). Undergoes
