Abstract:
The use of optogenetic approaches has revealed new roles for intracellular protein condensates described in two papers in this issue of Cell (Bracha et. al., 2018; Shin et al., 2018). These results show that growing condensates are able to exert mechanical forces resulting in chromatin rearrangement, establishing a new role for liquid-liquid phase separation in the mechanobiology of the cell.
