DEAD-box ATPases as master regulators of phase-separated compartments to control cellular RNA flux and the remodeling of RNA-protein complexes

Life ultimately depends on the tight control of gene expression, which requires an ordered and efficient processing of various RNA molecules. Messenger RNAs (mRNAs) – bound by a constantly changing coat of passenger proteins - transit from transcription in the nucleus to translation and ultimately decay in the cytoplasm. Similarly, ribosomal rRNAs migrate through the nucleolus where they gradually en-counter ribosomal proteins to assemble functional ribosomes. Still, we know very little about the pro-cesses that orchestrate this flux of RNA in a temporal and spatial manner. Intriguingly, many RNA processing steps occur in membraneless organelles formed by liquid-liquid phase separation,…
