Evaluating phase separation in live cells: diagnosis, caveats, and functional consequences

DT McSwiggen, M Mir, X Darzacq…�- Genes &�…, 2019 - genesdev.cshlp.org
The idea that liquid–liquid phase separation (LLPS) may be a general mechanism by which
molecules in the complex cellular milieu may self-organize has generated much excitement�…

[HTML][HTML] “Structure”-function relationships in eukaryotic transcription factors: the role of intrinsically disordered regions in gene regulation

JJ Ferrie, JP Karr, R Tjian, X Darzacq�- Molecular Cell, 2022 - cell.com
