Abstract

We have identified a virus-activated factor (VAF) that binds to a regulatory element shared by different virus-inducible genes. We provide evidence that VAF contains two members of the interferon regulatory factor (IRF) family of transcriptional activator proteins (IRF-3 and IRF-7), as well as the transcriptional coactivator proteins p300 and CBP. Remarkably, VAF, as well as recombinant IRF-3 and IRF-7 proteins, binds very weakly to the interferon-beta (IFN-beta) gene promoter in vitro. However, in virus-infected cells, both proteins are recruited to the endogenous IFN-beta promoter as part of a protein complex that includes ATF-2/c-Jun and NF-kappa B. These observations provide a unique example of the coordinate activation of multiple transcriptional activator proteins and their highly cooperative assembly into a transcriptional enhancer complex in vivo.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
