Mechanobiology of Protein Droplets: Force Arises from Disorder.
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.
