Web1 day ago · STING recruitment of TBK1 and IRF3 results in IRF3 phosphorylation by TBK1 and IRF3 55 nuclear translocation[18, 19]. Activated STING also activates IKK and the NF-κB family of 56 transcription factors[20], which with IRF3, activate expression of type I IFN and subsequently 57 ISGs.

WebOct 22, 2024 · Upon phosphorylation, IRF3 has to leave the adaptor as a monomer and the recently added phosphorylation will be exposed to cellular phosphatases. However, when phosphorylation occurs within these ‘signaling hubs’, IRF3 is likely to meet a similar phosphorylated IRF3 molecule, which allows for the formation of the stable homodimer … WebOct 28, 2024 · After treatment with mtDNA, the phosphorylation of TBK1 and IRF3 gradually increased and IRF3 aggregated in the nucleus rather than in the cytosol. NF-κB is a regulatory molecule that promotes the expression of some proinflammatory factors, and is also phosphorylated as a consequence of the full activation of TBK1 [ 33 ].
WebMar 5, 2024 · IRF3 is a key transcription factor for IFN-β expression. We next examined the effects of RNF39 on IRF3 activation. Rnf39 deficiency and knockdown both enhanced RNA virus–induced IRF3 phosphorylation (Fig. 2, A to C, and fig. S3D). Furthermore, RNF39 overexpression inhibited RIG-I– and MDA5-induced IRF3 reporter activation (Fig. 2D). … WebSep 19, 2013 · IRF3 is a constitutively expressed transcription factor that resides in the cytoplasm and dimerizes and translocates to the nucleus upon phosphorylation ().Phosphorylated IRF3 induces IFN-β during viral infection, but may also contribute to inflammatory cytokine response to LPS ().IRF3 also promotes apoptosis in virus-infected …
WebAug 13, 2024 · We found that ORF7b promoted expression of IFN-β, TNF-α and IL-6, activated type-I IFN signaling through IRF3 phosphorylation, and activated TNFα-induced apoptosis in HEK293T cells and Vero E6 cells. These results could provide deeper understanding about the pathogenicity of SARS-CoV-2as well as the interaction between … WebMar 12, 2015 · IRF3 activation requires phosphorylation, dimerization and nuclear translocation. However, the mechanisms for the termination of IRF3 activation in nucleus are elusive. Here we report the identification of TRIM26 to negatively regulate IFN-β production and antiviral response by targeting nuclear IRF3.
WebControl of IRF-3 activation by phosphorylation. Interferon (IFN) regulatory factor-3 (IRF-3) is a unique member of the IRF family. Its transcriptional activity is regulated solely by …
