Cell shrinkage, which occurs in a hypertonic environment, results in a rapid rebound response to restore cell volume and ion concentrations. In a recent study published in Cell, Boyd-Shiwarski et al. identify WNK1, a known homeostatic regulator of cell volume, as a molecular crowding sensor, and demonstrate how WNK1 contributes to cell volume recovery through cell shrinkage-dependent phase separation.
