IRF3 and IRF7 (IRF3/IRF7) are the two major members of the interferon regulatory factor (IRF) family, involved in modulating the IFN gene expression. However, their roles are different in these processes. In the early phase of viral infection, preexisting IRF-3 is activated and induces expression of IFN beta and IFN alpha4. These early produced IFNs transcriptionally induce IRF-7, and upon viral infection, the induced high-level IRF-7 is activated and transactivates multiple IFN genes, leading to robust production of IFNs in response to viral infection. IPS-1 interacts with both IRF3 and IRF7 and recruits them to RIG-1. TBK1/IKKi kinases phosphorylate and activate IRF3/IRF7.
