Target Information

IFR3 (interferon regulatory factor 3) is a key transcriptional regulator of type I interferon (IFN)-dependent immune responses. It plays a critical role in the innate immune response against DNA and RNA viruses. IFR3 regulates the transcription of type I IFN genes (IFN-alpha and IFN-beta) and IFN-stimulated genes (ISG) by binding to an interferon-stimulated response element (ISRE) in their promoters.
It acts as a more potent activator of the IFN-beta gene than the IFN-alpha gene and plays a critical role in both the early and late phases of the IFNA/B gene induction.
IFR3 is found in an inactive form in the cytoplasm of uninfected cells and following viral infection, double-stranded RNA, or toll-like receptor signaling. It is phosphorylated by IKBKE and TBK1 kinases, inducing a conformational change that leads to dimerization, nuclear localization, and association with CREB binding protein to form dsRNA-activated factor 1 (DRAF1). This complex activates transcription of type I IFN and ISG genes.
Mutations in the gene can result in encephalopathy, acute, infection-induced, herpes-specific 7.
