Interplay of dynamic genome organization and biomolecular condensates

Curr Opin Cell Biol. 2023 Oct 6;85:102252. doi: 10.1016/j.ceb.2023.102252. Online ahead of print.ABSTRACTAfter 60 years of chromatin investigation, our understanding of chromatin organization has evolved from static chromatin fibers to dynamic nuclear compartmentalization. Chromatin is embedded in a heterogeneous nucleoplasm in which molecules are grouped into distinct compartments, partitioning nuclear space through phase separation. Human genome organization affects transcription which controls euchromatin formation by excluding inactive chromatin. Chromatin condensates have been described as either liquid-like or solid-like. In this short review, we discuss the dynamic nature of chromatin from the perspective of biomolecular condensates and highlight new live-cell synthetic tools to probe and manipulate chromatin organization and associated condensates.PMID:37806293 | DOI:10.1016/j.ceb.2023.102252
