question: Which transcription factors (TFs) participate in the formation of the interferon-beta (IFN-b) enhanceosome?
answer: Transcriptional activation of the IFN beta gene in response to virus infection requires the assembly of an enhanceosome, consisting of the transcriptional activators NF-kappa B, IRF1, ATF2/c-Jun, and the architectural protein HMG I(Y).  Transcriptional activation of the human interferon-beta (IFN-beta) gene by virus infection requires the assembly of a higher order nucleoprotein complex, the enhanceosome, which consists of the transcriptional activators NF-kappa B (p50/p65), ATF-2/c-jun, IRF-3 and IRF-7, architectural protein HMGI(Y), and the coactivators p300 and CBP.
