Nontranscriptional Activity of Interferon Regulatory Factor 3 Protects Mice From High‐Fat Diet‐Induced Liver Injury
Carlos Sanz‐Garcia, Megan R. McMullen, Saurabh Chattopadhyay, Sanjoy Roychowdhury, Ganes Sen, Laura E. Nagy – 10 October 2019 – Interferon regulatory factor 3 (IRF3) has both transcriptional and nontranscriptional functions. Transcriptional activity is dependent on serine phosphorylation of IRF3, while transcription‐independent IRF3‐mediated apoptosis requires ubiquitination. IRF3 also binds to inhibitor of nuclear factor kappa B kinase (IKKβ) in the cytosol, restricting nuclear translocation of p65.
