    Stepwise polarisation of developing bilayered epidermis is mediated by aPKC and E-cadherin in zebrafish

    Prateek Arora et al.
    Polarity cascade initiated by aPKC in the periderm is transduced by adherens junction component E-cadherin to the basal epidermis during the development of zebrafish bilayered epidermis.

    Conformational dynamics of the nucleotide binding domains and the power stroke of a heterodimeric ABC transporter

    Smriti Mishra et al.
    The conformational cycle of an ABC heterodimeric transporter reveals a divergence in the structural mechanism of ABC exporters.

    Conformational and dynamic plasticity in substrate-binding proteins underlies selective transport in ABC importers

    Marijn de Boer et al.
    Selective import via bacterial ABC importers is facilitated by a hitherto unrecognized complexity in the conformational dynamics of the substrate-binding proteins.

    A single power stroke by ATP binding drives substrate translocation in a heterodimeric ABC transporter

    Erich Stefan et al.
    Single-turnover studies reveal quantitative insights into the inner mechanics and unfold hidden facets in the conformational coupling of ATP binding, hydrolysis, and substrate translocation by ABC transporters.

    APP modulates KCC2 expression and function in hippocampal GABAergic inhibition

    Ming Chen et al.
    APP interacts with KCC2 to limit the latter from tyrosine-phosphorylation and ubiquitination and thus subsequent degradation, revealing a novel molecular pathway in which APP regulates GABAergic signaling and thus inhibition in the hippocampus.

    Structure of MlaFB uncovers novel mechanisms of ABC transporter regulation

    Ljuvica R Kolich et al.
    Structure of MlaFB reveals how a small binding protein and the C-terminal tail on an ATPase subunit work together to regulate the assembly and function of an ABC transporter.

    Exploring conformational equilibria of a heterodimeric ABC transporter

    M Hadi Timachi et al.
    A heterodimeric exporter exhibits conformational equilibria in the presence of nucleotides, suggesting a unified mechanistic model for the conformational cycle of ABC exporters.

    Opposite changes in APP processing and human Aβ levels in rats carrying either a protective or a pathogenic APP mutation

    Marc D Tambini et al.
    APP mutations that either cause or prevent dementia alter APP metabolism in a complex and opposite fashion, suggesting a link between multiple APP processing events, dementia and ageing-dependent cognitive decline.

    NECAPs are negative regulators of the AP2 clathrin adaptor complex

    Gwendolyn M Beacham et al.
    Endocytosis is regulated by a protein family that recycles the AP2 clathrin adaptor by restoring the inactive form of complex.
    1. Cell Biology

    The membrane-associated proteins FCHo and SGIP are allosteric activators of the AP2 clathrin adaptor complex

    Gunther Hollopeter et al.
    Endocytosis is triggered by membrane-associated proteins that transform the clathrin adaptor into an active complex.
