Immediately following initiation Pol II becomes trapped in promoter proximal paused positions on the majority of human genes (Figure 1). P-TEFb is a cyclin dependent kinase that can phosphorylate the DRB sensitivity inducing factor (DSIF) and negative elongation factor (NELF), as well as the carboxyl terminal domain of the large subunit of Pol II and this causes the transition into productive elongation leading to the synthesis of mRNAs. P-TEFb is regulated in part by a reversible association with the 7SK snRNP. Treatment of cells with the P-TEFb inhibitors DRB or flavopidirol leads to loss of mRNA production and ultimately cell death."@en }
