    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.

    Cytosolic aggregation of mitochondrial proteins disrupts cellular homeostasis by stimulating the aggregation of other proteins

    Urszula Nowicka, Piotr Chroscicki ... Agnieszka Chacinska
    Defective mitochondrial protein import results in protein aggregation and a specific chaperone response in the cytosol, causatively linking mitochondrial function and cellular protein homeostasis disturbances observed in neurodegeneration.

    Human LINE-1 retrotransposition requires a metastable coiled coil and a positively charged N-terminus in L1ORF1p

    Elena Khazina, Oliver Weichenrieder
    Human LINE-1 retrotransposition is found to critically depend on the rapidly evolving N-terminal sequence of the LINE-1 ORF1 protein and on the metastability of its coiled coil domain, indicating uncharacterized steps in LINE-1 retrotransposition.

    Empowering AlphaFold2 for protein conformation selective drug discovery with AlphaFold2-RAVE

    Xinyu Gu, Akashnathan Aranganathan, Pratyush Tiwary
    AlphaFold2's inability to generate non-native conformations for docking is addressed by AI-molecular dynamics method AlphaFold2-RAVE, which produces Boltzmann-ranked conformations, enabling the retrospective discovery of type II kinase inhibitors.

    Heterogeneous levels of delta-like 4 within a multinucleated niche cell maintains muscle stem cell diversity

    Susan Eliazer, Xuefeng Sun ... Andrew S Brack
    A gradient of Mib1-Dll4 within multinucleated muscle fibers maintains a continuum of metastable states within the muscle stem cell pool during tissue homeostasis.

    Hybrid protein assembly-histone modification mechanism for PRC2-based epigenetic switching and memory

    Cecilia Lövkvist, Pawel Mikulski ... Martin Howard
    Extra protein memory storage elements with positive feedbacks, in addition to histone modifications, can explain epigenetic switching and memory at the PRC2 target gene FLOWERING LOCUS C (FLC).

    Targeting DNA topoisomerases or checkpoint kinases results in an overload of chaperone systems, triggering aggregation of a metastable subproteome

    Wouter Huiting, Suzanne L Dekker ... Steven Bergink
    Various genotoxic stresses trigger widespread aggregation of abundant, liquid-liquid phase separation-prone proteins, suggesting that genotoxic stress is a potential driver of disease-associated protein aggregation.

    A physical mechanism of TANGO1-mediated bulky cargo export

    Ishier Raote, Morgan Chabanon ... Felix Campelo
    TANGO1 functions as a linactant filament to stabilize shallow COPII-coated buds, and after which membrane tension regulation, possibly mediated by TANGO1-controlled membrane fusion, facilitates bud elongation for procollagen export.

    A tug of war between filament treadmilling and myosin induced contractility generates actin rings

    Qin Ni, Kaustubh Wagh ... Garegin A Papoian
    Actin networks form clusters under myosin-induced contractility, while high actin filament treadmilling speed can reshape actin networks into ring-like structures with lower mechanical energy.

    The dynamic conformational landscape of the protein methyltransferase SETD8

    Shi Chen, Rafal P Wiewiora ... Minkui Luo
    Integrated experimental-computational approaches were implemented to reveal the dynamic conformational landscape of a biologically relevant protein methyltransferase SETD8 for functional annotation.
