  • 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.
  • Tissue specificity

  • Sequence similarities

    Belongs to the MAGUK family.
    Contains 1 guanylate kinase-like domain.
    Contains 3 PDZ (DHR) domains.
    Contains 1 SH3 domain.
  • Domain

    The PDZ domain 3 mediates interaction with ADR1B.
    The L27 domain near the N-terminus of isoform 2 is required for HGS/HRS-dependent targeting to postsynaptic density.
  • Post-translational

    Palmitoylation of isoform 1 is required for targeting to postsynaptic density.
  • Cellular localization

    Cell membrane. Cell junction, synapse, postsynaptic cell membrane, postsynaptic density. Cell projection, axon. Cell junction, synapse. 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.
