Promoter-proximal RNA polymerase II termination regulates transcription during human cell type transition


ABSTRACT: Metazoan gene transcription by RNA polymerase (Pol) II is regulated in the promoter-proximal region. Pol II can undergo termination in the promoter-proximal region, but whether this can contribute to transcription regulation in cells remains unclear. Here, we extend our previous multi-omics analysis to quantify changes in transcription kinetics during a human cell type transition event. We observe that upregulation of transcription involves an increase in initiation frequency and, at a set of genes, a decrease in promoter-proximal termination. In turn, downregulation of transcription involves a decrease in initiation frequency and an increase in promoter-proximal termination. Thus, promoter-proximal termination of Pol II contributes to the regulation of human gene transcription.
