    The Chd1 chromatin remodeler shifts hexasomes unidirectionally

    Robert F Levendosky, Anton Sabantsev ... Gregory D Bowman
    Oriented hexasomes can be generated using the Widom 601 positioning sequence, which enables straightforward production of nucleosomes with asymmetrically modified H2A/H2B dimers.

    Multiple selection filters ensure accurate tail-anchored membrane protein targeting

    Meera Rao, Voytek Okreglak ... Shu-ou Shan
    Biochemical dissections show that the Guided Entry of Tail Anchored proteins (GET) pathway selects ER-destined tail-anchored proteins using at least two distinct molecular mechanisms, each recognizing a distinct physicochemical feature in the substrate.

    Implications of the differing roles of the β1 and β3 transmembrane and cytoplasmic domains for integrin function

    Zhenwei Lu, Sijo Mathew ... Roy Zent
    Diverse biophysical properties of β1 and β3 integrin transmembrane and cytoplasmic domains result in distinct mechanisms of integrin activation and function.

    Atomic structures of fibrillar segments of hIAPP suggest tightly mated β-sheets are important for cytotoxicity

    Pascal Krotee, Jose A Rodriguez ... David S Eisenberg
    Atomic structures of hIAPP fibrillar segments, determined using the cryo electron microscopy method MicroED, reveal that strong, stable intermolecular interactions are important features of cytotoxic amyloid proteins.

    Assembling the Tat protein translocase

    Felicity Alcock, Phillip J Stansfeld ... Ben C Berks
    Evolutionary bioinformatics and experimentation are applied to the components of the Tat protein transport system to elucidate the structure of the membrane-bound receptor complex and to deduce a molecular description for its substrate-triggered activation.

    Relief of autoinhibition by conformational switch explains enzyme activation by a catalytically dead paralog

    Oleg A Volkov, Lisa Kinch ... Margaret A Phillips
    A catalytically dead paralog activates its cognate enzyme through an allosteric mechanism that combined structural and phylogenomic analysis indicates arose through acquisition of a dimerization domain, suggesting a general model for how complex allostery evolves.

    Ric-8A, a G protein chaperone with nucleotide exchange activity induces long-range secondary structure changes in Gα

    Ravi Kant, Baisen Zeng ... Stephen R Sprang
    Hydrogen-Deuterium exchange experiments show that Ric-8A induces similar dynamic changes in the structure of Gα as G protein-coupled receptors, yet protects a larger surface of the nucleotide-binding Ras domain.
