Irf3 phosphorylation site
WebAug 3, 2007 · The transcription factor interferon regulatory factor 3 (IRF-3) regulates genes in the innate immune response. IRF-3 is activated through phosphorylation by the kinases IKK epsilon and/or TBK1. Phosphorylation results in IRF-3 dimerization and removal of an autoinhibitory structure to allow interaction with the coactivators CBP/p300. WebApr 12, 2024 · The synergy between Jmjd8 knockdown and etoposide in regard to TBK1 and IRF3 phosphorylation, type I IFN and ISGs expression, and cytotoxicity was also seen in 4T-1 cells (Figures 6E–6H and S6D). We next injected nude mice subcutaneously with control or JMJD8-knockdown MCF7 cells and treated mice with or without etoposide.
