    Muscle calcium stress cleaves junctophilin1, unleashing a gene regulatory program predicted to correct glucose dysregulation

    Eshwar R Tammineni, Lourdes Figueroa ... Eduardo Rios
    Novel components in the pathway from malignant hyperthermia to diabetes include promotion of a kinase that impedes glycogen synthesis, increased lysis of junctophilin1 and gene regulatory actions by a junctophilin fragment, surprisingly predicted to oppose the effects of elevated calcium.

    Allosteric stabilization of calcium and phosphoinositide dual binding engages several synaptotagmins in fast exocytosis

    Janus RL Kobbersmed, Manon MM Berns ... Alexander M Walter
    A mathematical model of neurotransmitter release predicts that a mutual stabilization of calcium and membrane phospholipids binding to synaptotagmin proteins allows several synaptotagmins to work together for fast synaptic transmission.

    In vivo analysis reveals that ATP-hydrolysis couples remodeling to SWI/SNF release from chromatin

    Ben C Tilly, Gillian E Chalkley ... C Peter Verrijzer
    Visualization of BRM remodelers engaging their endogenous genomic targets revealed highly transient and dynamic interactions with chromatin, which are fueled by ATP-hydrolysis.

    Phagocytic glia are obligatory intermediates in transmission of mutant huntingtin aggregates across neuronal synapses

    Kirby M Donnelly, Olivia R DeLorenzo ... Margaret M Panning Pearce
    Prion-like transfer of mutant huntingtin aggregates from presynaptic to postsynaptic neurons is enhanced by neuronal silencing and requires passage through the cytoplasm of Draper-expressing phagocytic glia in adult Drosophila brains.

    Physical basis of the cell size scaling laws

    Romain Rollin, Jean-François Joanny, Pierre Sens
    A theoretical model explains how protein density and nuclear to cell volume ratio are maintained during cell growth, discusses conditions under which this breaks down, and highlights the importance of metabolites, mainly amino acids such as glutamate, in this homeostasis.

    The phage L capsid decoration protein has a novel OB-fold and an unusual capsid binding strategy

    Rebecca L Newcomer, Jason R Schrad ... Kristin N Parent
    The structure of phage L's Dec demonstrates a new fold within this family of proteins, and shows modulation of capsid binding occurs through two sites, with site 1 being preferred.

    Rapid binding to protofilament edge sites facilitates tip tracking of EB1 at growing microtubule plus-ends

    Samuel J Gonzalez, Julia M Heckel ... Melissa K Gardner
    Computational modeling combined with biophysical and cellular experiments reveal that rapid binding to incomplete, partial microtubule binding sites facilitates tracking of the end-binding protein EB1 with growing microtubule plus-ends.

    Mitochondrial protein import clogging as a mechanism of disease

    Liam P Coyne, Xiaowen Wang ... Xin Jie Chen
    Missense mutations in the nuclear-encoded adenine nucleotide translocase 1 (Ant1) cause the protein to clog the mitochondrial protein import pathway, to severely inhibit cell growth in yeast, and to cause neurodegeneration and myopathy in mice that phenocopy ANT1-induced human disease.

    A seven-sex species recognizes self and non-self mating-type via a novel protein complex

    Guanxiong Yan, Yang Ma ... Wei Miao
    A giant multifunctional protein complex mediates mating-type recognition through a non-ligand–receptor mechanism in a multisexual species.

    9Å structure of the COPI coat reveals that the Arf1 GTPase occupies two contrasting molecular environments

    Svetlana O Dodonova, Patrick Aderhold ... John A G Briggs
    A molecular model of the assembled COPI coat, determined by cryo-electron tomography of an in vitro reconstituted budding reaction, reveals details of interactions mediating coat assembly and shows the binding site of ArfGAP2.
