WebJan 8, 2024 · Transcriptional activation of the IFNβ promoter by IRF3/7 has been extensively studied (9, 10), and proceeds with phosphorylation of IRF3/7 by the kinase TKB1, leading to dimerization and translocation of IRF3/7 homo-or hetero-dimers to the nucleus together with other transcription factors, such as nuclear factor (NF)-κB and activator protein ... WebThe induction of phosphorylation of STING on S366 of IRF3 on S396 was inhibited in T404E compared to WT or T404A cells (Fig. 3C). We also found that IRF3 nuclear translocation ( Fig. 3 D and SI Appendix , Fig. S5 B ) and the induction of IRF3-dependent genes ( Fig. 3 E ) were substantially inhibited in cells expressing T404E-STAT2.
IRF3 is a member of the interferon regulatory transcription factor (IRF) family. IRF3 was originally discovered as a homolog of IRF1 and IRF2. IRF3 has been further characterized and shown to contain several functional domains including a nuclear export signal, a DNA-binding domain, a C-terminal IRF association domain and several regulatory phosphorylation sites. IRF3 is found … WebAug 21, 2024 · The NTD of IRF3 contains the DNA binding domain (45), and the CTD of IRF3 (containing the Ser385, Ser386, and Ser396 phosphorylation sites) includes the crucial region for its phosphorylation (46 ...
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 ]. WebAug 11, 2009 · However, despite the apparent redundancy between the IKK-related kinases, knock-out experiments suggest that TBK1, like IKKβ and its role in NF-κB activation, …
