Web25 jul. 2014 · Human RE transcriptional modulation by microbial stimulation is cell-intrinsic. To address this issue of cell composition in inflamed or healthy tissues, we analyzed the transcriptional activity of REs in specific human cell types either isolated ex vivo from human viral infection or exposed to microbial stimuli in vitro. Webactivator, RNA polymerase binds to the promoter, forms stable closed complex, however, no transition to open complex occurs and thus, there is no transcription. (B) Binding of activator to activator binding sequence brings about conformational change in RNA polymerase resulting in transition of the closed complex to open complex thereby …
