Post-Translational Modification, Phase Separation, and Robust Gene Transcription.

Abstract

A few recent reports reveal fundamental new insights into the intricate regulatory mechanisms that govern RNA polymerase II (Pol II)-mediated gene transcription. Whereas a histidine-rich domain (HRD) triggers phase separation, promoting transcription elongation, a phosphatase switch promotes transcription termination. A paradigm that might govern the underlying mechanisms leading to robust gene transcription is now starting to emerge.
