The promoter-proximal Pol II pausing regulation in metazoans includes the recruitment of CDK9 by JMJD6 and BRD4, the generation of a unique phosphorylation pattern of CTD of Pol II, the recruitment of JMJD5, and the cleavage of arginine methylated histone tails on the +1 nucleosome. We find that both BRD4 and p300/CBP control the activity of CDK9. It is likely that the BRD4 docking site on nucleosomes is generated by p300/CBP. We conclude that enhancer/enhanceosome/super-enhancer and Pol II pausing regulation are coupled and could be the unique universal mechanism that differentiates animals from unicellular organisms.\nCompeting Interest Statement\nGZ holds equity in NB Life Laboratory, LLC, Colorado, USA\nFootnotes\nConflicts of interest: GZ holds equity in NB Life Laboratory LLC","source_license":"Public-Domain","license_restricted":false}
