Intrinsically disordered proteins in overcrowded milieu: Membrane-less organelles, phase separation, and intrinsic disorder

Although the cellular interior is crowded with various biological macromolecules, the distribution of these macromolecules is highly inhomogeneous. Eukaryotic cells contain numerous proteinaceous membrane-less organelles (PMLOs), which are condensed liquid droplets formed as a result of the reversible and highly controlled liquid-liquid phase transitions. The interior of these cellular bodies represents an overcrowded milieu, since their protein...
