Summaries for DLG4 Gene

Entrez Gene Summary for DLG4 Gene

  • This 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. [provided by RefSeq, Jul 2008]

GeneCards Summary for DLG4 Gene

DLG4 (Discs, Large Homolog 4 (Drosophila)) is a Protein Coding gene. Diseases associated with DLG4 include schizophrenia. Among its related pathways are L1CAM interactions and L1CAM interactions. GO annotations related to this gene include protein C-terminus binding and ionotropic glutamate receptor binding. An important paralog of this gene is MPP6.

UniProtKB/Swiss-Prot for DLG4 Gene

  • 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).

Interacts through its first PDZ domain with GRIK2, KCNA4 and CRIPT. Interacts through its second PDZ domain with the PDZ domain of NOS1 or the C-terminus of CAPON. Interacts through its third PDZ domain with NLGN1 and CRIPT, and probably with NLGN2 and NLGN3. Interacts through its guanylate kinase-like domain with DLGAP1/GKAP, DLGAP2, DLGAP3, DLGAP4, MAP1A, BEGAIN, SIPA1L1 and KIF13B. Isoform 2 interacts through an L27 domain with HGS/HRS and the first L27 domain of CASK. Interacts with ADR1B, ANKS1B and PRR7. May interact with HTR2A. Interacts with ADAM22, KLHL17 and LGI1. Interacts with FRMPD4 (via C-terminus). Interacts with LRFN1, LRFN2 and LRFN4, but not with LRFN3 nor LRFN5. Interacts (via N-terminal tandem pair of PDZ domains) with GPER1 (via C-terminus tail motif); the interaction is direct and induces the increase of GPER1 protein levels residing at the plasma membrane surface in a estradiol-independent manner. Interacts (via N-terminus tandem pair of PDZ domains) with NOS1 (via N-terminal domain). Interacts with SHANK3. Interacts with KCNJ4 (By similarity).
