Interferon (IFN) regulatory factors (IRF) are a family of transcription factors with multiple functions. IRF-7 was initially cloned within the biologic context of Epstein-Barr virus (EBV) latency and discovered to have an intimate relation with the EBV primary oncogenic protein, latent membrane protein-1 (LMP-1). EBV regulates and uses IRF-7 as a secondary mediator for several target genes involved in latency and immune regulation. Other than its functions in EBV latency, IRF-7 has been identified as one of the major players in virally induced IFN production that is central to innate immunity. Thus, IRF-7 plays important roles in a variety of biologic systems.
