      Background InformationPSD95 (postsynaptic density95) represent a class of anchoring proteins which serve to localize various neuronal ion channels to post-synaptic densities. PSD95 and related proteins contain PDZ domains, which interact with NMDA receptors and voltage-gated K+ channels via a ET/SXV motif in the cytoplasmic carboxyl terminus of the receptor channels.

      Entrez Gene Number
      Entrez Gene SummaryThis gene encodes a member of the membrane-associated guanylate kinase (MAGUK) family. It heteromultimerizes with another MAGUK protein, DLG2, and is recruited into NMDA receptor and potassium channel clusters. These two MAGUK proteins may interact at postsynaptic sites to form a multimeric scaffold for the clustering of receptors, ion channels, and associated signaling proteins. Multiple transcript variants encoding different isoforms have been found for this gene.

      UniProt Number
      UniProt SummaryFUNCTION: 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 ACCN3 acid-evoked currents by retaining the channel intracellularly. May regulate the intracellular trafficking of ADR1B By similarity.
      SUBUNIT STRUCTURE: Interacts with ANKS1B and PRR7 By similarity. Interacts through its first two PDZ domains with GRIN2A, GRIN2B, GRIN2C, GRIN2D, ACCN3, certain splice forms of GRIN1, KCND2, CXADR and SYNGAP1. Interacts through its second PDZ domain with the PDZ domain of NOS1 or the C-terminus of CAPON. May interact with HTR2A. Interacts through its guanylate kinase-like domain with DLGAP1/GKAP, DLGAP2, DLGAP3, DLGAP4, MAP1A and BEGAIN. Interacts through its third PDZ domain with CRIPT By similarity. Interacts through its first two PDZ domains with KCNA1, KCNA2, KCNA3, KCNA4 and ERBB4. Interacts through its first PDZ domain with GRIK2, KCNA4 and CRIPT. Interacts through its third PDZ domain with NLGN1, and probably with NLGN2 and NLGN3. Interacts through its guanylate kinase-like domain with KIF13B. Isoform 2 interacts through an L27 domain with HGS/HRS and the first L27 domain of CASK. Interacts with LRFN1.
      SUBCELLULAR LOCATION: Cell membrane; Peripheral membrane protein. Cell junction › synapse › postsynaptic cell membrane › postsynaptic density. Cell junction › synapse. 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.
      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 post-synaptic density.
      PTM: Palmitoylation of isoform 1 is required for targeting to postsynaptic density By similarity.
      SEQUENCE SIMILARITIES: Belongs to the MAGUK family.
      Contains 1 guanylate kinase-like domain.
      Contains 3 PDZ (DHR) domains.
      Contains 1 SH3 domain.
      Molecular Weight~95 kDa
