Description

Interferon regulatory factors (IRF) IRF-3 and IRF-7 are the major modulators of IFN gene expression in response to pathogenic molecules. The relative contribution of IRF3 and IRF7 depends on the signaling pathway that is activated. Type I IFN production in cytosolic DNA-sensing pathway is mediated predominantly by IRF3 and partially by IRF7, since DNA-stimulated IFN-beta and IFN-alpha4 mRNA induction was strongly inhibited in IRF3-deficient mouse embryonic fibroblasts (MEFs), while remained normal (IFN-beta) or reduced (IFN-alpha4) in IRF7-deficient MEFs (Takaoke A et al 2007). IRF3 activation in response to B-DNA stimulation occurs via its co-recruitment with serine/threonine kinase TANK-binding kinase 1 (TBK1) or inducible IkB kinase (IKKi/IKKepsilon) to the C-terminal region of DAI.
