    How to measure and evaluate binding affinities

    Inga Jarmoskaite, Ishraq AlSadhan ... Daniel Herschlag
    Simple guidelines and a checklist are provided for performing high-quality equilibrium binding measurements.

    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.

    Mutations in SKI in Shprintzen–Goldberg syndrome lead to attenuated TGF-β responses through SKI stabilization

    Ilaria Gori, Roger George ... Caroline S Hill
    The mechanism underlying Shprintzen–Goldberg syndrome is solved and reveals that missense mutations in the transcriptional repressor SKI abolish ligand-induced SKI degradation, which results in attenuation of TGF-β transcriptional responses.

    Heterogeneity of the GFP fitness landscape and data-driven protein design

    Louisa Gonzalez Somermeyer, Aubin Fleiss ... Fyodor A Kondrashov
    Orthologous proteins display different mutational robustness that can be leveraged to improve prediction of functional sequences.

    Large protein complex interfaces have evolved to promote cotranslational assembly

    Mihaly Badonyi, Joseph A Marsh
    Analysis of protein interfaces suggests cotranslational assembly can be an adaptive process, likely serving to minimise non-specific interactions with other proteins in the cell.

    The interplay between asymmetric and symmetric DNA loop extrusion

    Edward J Banigan, Leonid A Mirny
    Models of chromosome compaction by condensins demonstrate that two-sided loop extrusion and long residence times are required for high compaction, suggesting a tight coupling between these two properties in vivo.

    Community diversity is associated with intra-species genetic diversity and gene loss in the human gut microbiome

    Naïma Madi, Daisy Chen ... Nandita R Garud
    Longstanding eco-evolutionary theories are tested using shotgun metagenomic data from the human gut microbiome, showing links between community diversity and the evolutionary trajectory of a focal species within the community.

    McsB forms a gated kinase chamber to mark aberrant bacterial proteins for degradation

    Bence Hajdusits, Marcin J Suskiewicz ... Tim Clausen
    The McsB kinase is critical for protein quality control in Gram-positive bacteria, assembling a gated phosphorylation chamber during heat-shock conditions to selectively mark misfolded proteins for degradation.

    Rate-limiting transport of positively charged arginine residues through the Sec-machinery is integral to the mechanism of protein secretion

    William J Allen, Robin A Corey ... Ian Collinson
    The time it takes to secrete a protein is dominated by diffusion of positively charged arginines through the channel across the membrane, but lysines avoid this problem as they are neutralised before transport.
