Publication Abstract from PubMed
Upon viral infection, NF-kappaB translocates to the nucleus and activates the IFN-beta gene by binding to the PRDII element. Strikingly, NF-kappaB loses its ability to activate the IFN-beta gene when the PRDII element is substituted by closely related sites. We report here the crystal structure of NF-kappaB p50/p65 heterodimer bound to the PRDII element from the IFN-beta promoter. The structure reveals an unexpected alteration in configuration, in which the p50 specificity domain moves by as much as approximately 9 A when compared to NF-kappaB heterodimer bound to the immunoglobulin kappaB site (Ig-kappaB) while maintaining the same base-specific contacts with the DNA. Taken together, the structure offers new insights into the allosteric effects of closely related DNA sites on the configuration of NF-kappaB and its transcriptional selectivity.
