    A novel N-terminal extension in mitochondrial TRAP1 serves as a thermal regulator of chaperone activity

    James R Partridge, Laura A Lavery ... David A Agard
    Cytosolic and organellar Hsp90s from higher eukaryotes have evolved a variable, and environmentally responsive N-terminal extension to regulate their activity.

    An unexpected role for the yeast nucleotide exchange factor Sil1 as a reductant acting on the molecular chaperone BiP

    Kevin D Siegenthaler, Kristeen A Pareja ... Carolyn S Sevier
    Building on previous work (Wang et al., 2014), it is shown that the nucleotide exchange factor of the chaperone BiP (Sil1) unexpectedly facilitates the reduction of oxidized BiP.

    Plasmodium-infected erythrocytes induce secretion of IGFBP7 to form type II rosettes and escape phagocytosis

    Wenn-Chyau Lee, Bruce Russell ... Laurent Renia
    Plasmodium parasites use host-derived factors to form more rosettes and hamper phagocytosis, representing a new escape mechanism for the malaria parasites.

    Determinantal point process attention over grid cell code supports out of distribution generalization

    Shanka Subhra Mondal, Steven Frankland ... Jonathan D Cohen
    Strong out of distribution generalization using an attentional mechanism over grid cell code inspired by determinantal point processes.

    Helix breaking transition in the S4 of HCN channel is critical for hyperpolarization-dependent gating

    Marina A Kasimova, Debanjan Tewari ... Baron Chanda
    The gating polarity of a voltage-gated ion channel is primarily determined by turn propensity of residues at a critical position in the middle of the S4 voltage-sensing helix.

    Humans optimally anticipate and compensate for an uneven step during walking

    Osman Darici, Arthur D Kuo
    Humans can predict and optimally plan goal-directed dynamic walking tasks that have transient events such as negotiating a sidewalk curb.

    The potassium channel subunit KV1.8 (Kcna10) is essential for the distinctive outwardly rectifying conductances of type I and II vestibular hair cells

    Hannah R Martin, Anna Lysakowski, Ruth Anne Eatock
    A striking and consequential conductance in vestibular type I hair cells is finally shown to depend on a little-known Shaker subunit that contributes to conventional conductances in other hair cells.
