Genome-wide studies have demonstrated that the phenomenon of promoter-bound Pol II pausing is widespread, especially for genes involved in developmental and stimulus-responsive pathways. Here, Chen et al. used the small molecule triptolide (TPL), an XPB/TFIIH inhibitor, to block transcriptional initiation and then measured Pol II occupancy by ChIP-seq. This revealed that most genes with paused Pol II show significant clearance of Pol II during the period of TPL treatment. They also identified a group of genes with unexpectedly stably paused Pol II, with unchanged Pol II occupancy during 1 h of inhibition of initiation.
