    Constitutive auxin response in Physcomitrella reveals complex interactions between Aux/IAA and ARF proteins

    Meirav Lavy et al.
    The auxin-sensitive Aux/IAA transcriptional repressors regulate approximately 35% of the annotated genes in Physcomitrella patens and exhibit complex interactions with both the activating and repressing ARF transcription factors.

    Age-related changes in polycomb gene regulation disrupt lineage fidelity in intestinal stem cells

    Helen M Tauc et al.
    Global, multi-angled genetic analyses identified an age-associated loss of stem cell lineage fidelity that was linked to changes in polycomb regulation in the Drosophila intestinal epithelium.

    Characterization of the ABC methionine transporter from Neisseria meningitidis reveals that lipidated MetQ is required for interaction

    Naima G Sharaf et al.
    NmMetQ is a lipoprotein that tethers to membranes via a lipid anchor and has dual function and localization, playing a role in NmMetNI-mediated transport at the inner membrane and moonlighting on the bacterial surface.

    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.

    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.

    Three-dimensional growth of breast cancer cells potentiates the anti-tumor effects of unacylated ghrelin and AZP-531

    CheukMan C Au et al.
    3D culture of breast cancer in biologically relevant ECM potentiates the growth-inhibitory effects of unacylated ghrelin and AZP-531, and clinical response may be predictable based on a MAPK gene signature.

    MicroRNA-mediated repression of nonsense mRNAs

    Ya Zhao et al.
    microRNAs can serve as a surveillance system to repress nonsense mRNAs by recognizing miRNA-responsive elements in the open reading frame region downstream of the premature termination codon.
