一般說明

DLG4 (discs large homolog 4) gene is localized to human chromosome 17p13.1. It is an abundantly present scaffolding protein. It is a multi-domain protein, which is a member of the membrane-associated guanylate kinase (MAGUK) family of proteins. This protein family is characterized by PSD-95/discs large/ZO-1 (PDZ)-Src homology 3 (SH3)-guanylate kinase domain. DLG4 is localized to the cytoplasmic ends of postsynaptic terminals.

生化/生理作用

Knockout (KO) mice for DLG4 (discs large homolog 4) are characterized by aberrant synaptic plasticity and impaired spatial learning. Polymorphisms in this gene at the core promoter region and the 3′ and 5′ UTR (untranslated regions) control its expression, which in turn is associated with susceptibility to schizophrenia. It couples the activity of N-methyl-D-aspartate receptors (NMDARs) to neurotoxicity by NO (nitric oxide), and is also responsible for specificity to excitotoxic Ca2+ signaling. This protein functions in the postsynapse at excitatory neurons, where it is responsible for the clustering of glutamate receptors and organization of macromolecular complexes for signal integration. In Alzheimer′s diseases, an increase in the expression of this protein is linked with increase in β-amyloid and phosphorylated Tau proteins.

特點和優勢

Prestige Antibodies® are highly characterized and extensively validated antibodies with the added benefit of all available characterization data for each target being accessible via the Human Protein Atlas portal linked just below the product name at the top of this page. The uniqueness and low cross-reactivity of the Prestige Antibodies® to other proteins are due to a thorough selection of antigen regions, affinity purification, and stringent selection. Prestige antigen controls are available for every corresponding Prestige Antibody and can be found in the linkage section.

Every Prestige Antibody is tested in the following ways:
  • IHC tissue array of 44 normal human tissues and 20 of the most common cancer type tissues.
  • Protein array of 364 human recombinant protein fragments.

In order to understand how plasticity is related to neurodegeneration, we studied synaptic proteins with quantitative immunohistochemistry in the entorhinal cortex from Alzheimer patients and age-matched controls. We observed a significant decrease in presynaptic synaptophysin and an increase in postsynaptic

Postsynaptic density-95 is a multidomain scaffolding protein that recruits glutamate receptors to postsynaptic sites and facilitates signal processing and connection to the cytoskeleton. It is the leading member of the membrane-associated guanylate kinase family of proteins, which are defined by

Hypofunction of N-methyl-D-aspartate (NMDA) receptor-mediated signal transduction has been implicated in the pathophysiology of schizophrenia. Post-synaptic density protein 95 (PSD95) plays a critical role in regulating the trafficking and activity of the NMDA receptor and altered expression of the PSD95

The efficiency with which N-methyl-D-aspartate receptors (NMDARs) trigger intracellular signaling pathways governs neuronal plasticity, development, senescence, and disease. In cultured cortical neurons, suppressing the expression of the NMDAR scaffolding protein PSD-95 (postsynaptic density-95) selectively attenuated excitotoxicity triggered via NMDARs, but
