%0 Journal Article %T Phase Separation, Transition, and Autophagic Degradation of Proteins in Development and Pathogenesis %J - %D 2019 %R https://doi.org/10.1016/j.tcb.2019.01.008 %X Protein condensates are assembled via phase separation and exhibit distinct material properties (e.g., liquid, gel-like, or solid state). The biophysical properties of protein condensates are important for their distinct cellular functions. The liquid-to-amyloid-like fibrillization of protein condensates is prevented by chaperones such as HSP70 and TNPO1 and facilitated by protein mutations and by cosegregation of misfolded proteins. The aberrant solid-state transition of protein condensates is associated with the pathogenesis of various diseases. Receptor proteins, scaffold proteins, and PTMs control the size, formation rate, and biophysical properties of phase-separated protein condensates, which in turn determine their autophagic degradation or accumulation under various developmental conditions %U https://www.cell.com/trends/cell-biology/fulltext/S0962-8924(19)30019-4
