    Oscillatory phase separation in giant lipid vesicles induced by transmembrane osmotic differentials

    Kamila Oglęcka, Padmini Rangamani ... Atul N Parikh
    Spontaneous osmoregulation in giant phospholipid vesicles, which is characterized by oscillations in vesicle size and membrane tension, couples to the compositional degrees of freedom at the membrane surface to produce oscillations in domain texture and induce isothermal phase change.

    Decoding the physical principles of two-component biomolecular phase separation

    Yaojun Zhang, Bin Xu ... Ned S Wingreen
    Phase separation of two-component multivalent systems is suppressed at rational polymer stoichiometries, suggesting possible cellular strategies for regulating the formation and function of biomolecular condensates.

    Protein sorting by lipid phase-like domains supports emergent signaling function in B lymphocyte plasma membranes

    Matthew B Stone, Sarah A Shelby ... Sarah L Veatch
    Clustering the B cell receptor generates a membrane domain analogous to the liquid-ordered phase, localizing proteins involved in early receptor activation.

    Pre-transition effects mediate forces of assembly between transmembrane proteins

    Shachi Katira, Kranthi K Mandadapu ... David Chandler
    A general mechanism for how powerful forces of assembly and protein mobility can emerge from phase transitions is established.

    Dynamic metastable long-living droplets formed by sticker-spacer proteins

    Srivastav Ranganathan, Eugene I Shakhnovich
    Multi-scale simulations reveal a potential, ATP-independent mechanism resulting in the formation of the long-living multi-droplet state by multi-valent, spacer-sticker proteins.

    The Mla pathway in Acinetobacter baumannii has no demonstrable role in anterograde lipid transport

    Matthew J Powers, Brent W Simpson, M Stephen Trent
    An outer membrane vesicle pulse-chase assay demonstrates that the Acinetobacter baumannii Mla system is a retrograde lipid transporter.

    Evidence for DNA-mediated nuclear compartmentalization distinct from phase separation

    David Trombley McSwiggen, Anders S Hansen ... Xavier Darzacq
    Transient DNA interactions by DNA-binding proteins are utilized by herpes simple virus as an alternative route to generate membraneless compartments in the nucleus without invoking phase separation.

    Chronic optogenetic induction of stress granules is cytotoxic and reveals the evolution of ALS-FTD pathology

    Peipei Zhang, Baochang Fan ... J Paul Taylor
    OptoGranules reveal the function of G3BP1 as a stress granule scaffold and demonstrate that protracted stress granule assembly is sufficient to drive neurodegeneration and the evolution of ALS-FTD pathology.
