    Experiments using endogenous and biomimetic condensates in cells show that nucleation in cells resembles the physical process in inanimate materials, but is tuned by biomolecular features.

    Phase separation properties are a major determinant of UTX activity in chromatin regulation in tumour suppression, and are dependent on a core intrinsically disordered region of the protein.

    The surfactant-like protein Ki-67 mediates the clustering of chromosomes during mitotic exit, which displaces large cytoplasmic molecules from the future nuclear space and thus enables the separation of cytoplasmic and nuclear components before the nuclear envelope reforms.

    The adaptability of the plant Arabidopsis thaliana to different temperatures is regulated by the ability of its ELF3 protein to undergo liquid–liquid phase separation, in a manner that is dependent on the protein’s prion-like domain.

    The chromatin protein MeCP2 is a component of dynamic, liquid-like heterochromatin condensates, and the ability of MeCP2 to form condensates is disrupted by mutations in the MECP2 gene that occur in the neurodevelopmental disorder Rett syndrome.

    The carboxy terminus of human UDP-α-d-glucose-6-dehydrogenase is structurally disordered, but has sequence-independent effects on the conformation of the enzyme and binding of an allosteric inhibitor, suggesting a reason for the persistence of intrinsically disordered peptide segments in the proteome.

    ZNFX-1 and WAGO-4 localize to germ granules in early Caenorhabditis elegans embryogenesis and later separate to form independent liquid-like droplets, and the temporal and spatial ordering of these droplets may help cells to organize complex RNA processing pathways.

    A high-affinity complex of histone H1 and prothymosin-α reveals an unexpected interaction mechanism, where the large opposite net charge enables the two proteins to remain highly disordered even in the complex.

    HP1a can nucleate into foci that display liquid properties during the early stages of heterochromatin domain formation in Drosophila embryos, suggesting that the repressive action of heterochromatin may be mediated in part by emergent properties of phase separation.

    The intrinsically disordered CITED2 negative feedback regulator displaces the tightly bound hypoxia-inducible transcription factor HIF-1α from their common target TAZ1 through the formation of an intermediate ternary complex and thereby attenuates the hypoxic response.

    Atomic resolution in-cell NMR and EPR spectroscopy show that the human amyloid protein α-synuclein remains disordered within all mammalian cells tested, including neurons, and identifies which parts of the protein dynamically interact or remain shielded from the cytoplasm, thus counteracting aggregation under physiological cell conditions.

    Single-molecule FRET is used to examine how an intrinsically disordered protein, the adenovirus E1A oncoprotein, interacts with two different protein partners (the pocket domain of pRb and the TAZ2 domain of CBP/p300); the biophysical behaviour of E1A depends on whether the N-terminal region and/or the CR2 region of E1A is free to interact with potential protein partners or whether they are ‘masked’ (that is, via their absence or a pre-existing interaction with another protein partner).
