    Cryo-EM structures reveal specialization at the myosin VI-actin interface and a mechanism of force sensitivity

    Pinar S Gurel et al.
    Cryo-EM structures of actomyosin VI in multiple nucleotide states reveal a unique actin-myosin interface and a mechanism of force-sensitivity; furthermore, myosin VI remodels F-actin, suggesting a role for actin structural plasticity during force generation.

    Membrane transporter dimerization driven by differential lipid solvation energetics of dissociated and associated states

    Rahul Chadda et al.
    Differences in the lipid solvation energetics of associated and dissociated states is a primary driving force for membrane protein oligomerization, presenting a molecular mechanism for lipid regulation in biology.

    Glycolytic preconditioning in astrocytes mitigates trauma-induced neurodegeneration

    Rene Solano Fonseca et al.
    Promoting a Warburg-like shift in astrocytic metabolism through reduced mitochondrial electron transport accommodates the energetic burden caused by brain trauma without overwhelming cellular respiration and redox to salvage dopaminergic neurons.

    N501Y mutation of spike protein in SARS-CoV-2 strengthens its binding to receptor ACE2

    Fang Tian et al.
    Spike protein of SARS-CoV-2 with mutation N501Y shows a faster association rate, slower dissociation rate, and higher binding probability and unbinding force to its human receptor protein ACE2, leading to higher transmission.

    Ecdysone steroid hormone remote controls intestinal stem cell fate decisions via the PPARγ-homolog Eip75B in Drosophila

    Lisa Zipper et al.
    A systemic hormone controls progenitor fate decisions independent of local fate determining pathways in the adult intestinal stem cell niche of Drosophila melanogaster..

    Transverse tubule remodeling enhances Orai1-dependent Ca2+ entry in skeletal muscle

    Antonio Michelucci et al.
    Structural and functional analyses show that transverse tubule association with stacks of sarcoplasmic reticulum enhances Orai1-dependent Ca2+ entry to replenish Ca2+ stores, maintain Ca2+ release, and maximize force during exercise.
