研究背景

功能:

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.

翻译修饰:

Palmitoylated. Palmitoylation is required for targeting to postsynaptic density, plasma membrane and synapses (By similarity). Palmitoylation may play a role in glutamate receptor GRIA1 synapse clustering (By similarity). Depalmitoylated by ABHD17A and ABHD17B and to a lesser extent by ABHD17C, ABHD12, ABHD13, LYPLA1 and LYPLA2. Undergoes rapid synaptic palmitoylation/depalmitoylation cycles during neuronal development which slow down in mature neurons (By similarity).

Ubiquitinated by MDM2 in response to NMDA receptor activation, leading to proteasome-mediated degradation of DLG4 which is required for AMPA receptor endocytosis.

Interacts (via PDZ3 domain and to lesser degree via PDZ2 domain) with PRR7 (By similarity). Component of the postsynaptic hippocampal AMPA-type glutamate receptor (AMPAR) complex, at least composed of pore forming AMPAR subunits GRIA1, GRIA2 and GRIA3 and AMPAR auxiliary proteins SHISA6 and SHISA7. Interacts (via its first two PDZ domains) with SHISA6 and SHISA7 (via PDZ-binding motif); the interaction is direct (By similarity). Interacts with RPH3A and GRIN2A; this ternary complex regulates NMDA receptor composition at postsynaptic membranes (By similarity). Interacts with ABR and BCR.
