    HDX-MS reveals structural determinants for RORγ hyperactivation by synthetic agonists

    Timothy S Strutzenberg et al.
    Unique methodology was used to generate a large HDX-MS dataset to inform ligand-mediated activation of RORγ, an approach that can be extended to other nuclear receptors with unresolved ligand-dependent activities.

    An open-source computational and data resource to analyze digital maps of immunopeptidomes

    Etienne Caron et al.
    A community-based international effort generates standardized HLA allele-specific peptide assay libraries and enables the analysis of the human immunopeptidome by SWATH mass spectrometry.

    The autophagy adaptor NDP52 and the FIP200 coiled-coil allosterically activate ULK1 complex membrane recruitment

    Xiaoshan Shi et al.
    Hydrogen-deuterium exchange, electron microscopy, and vesicle reconstitution show how binding of the autophagy adaptor NDP52 to the FIP200 subunit of the ULK1 complex triggers membrane binding in autophagy.

    Functional roles of Mg2+ binding sites in ion-dependent gating of a Mg2+ channel, MgtE, revealed by solution NMR

    Tatsuro Maruyama et al.
    Nuclear magnetic resonance analysis revealed the structural and dynamical changes in MgtE during the channel closure caused by the cooperative Mg2+-binding, which had remained undescribed only by a static crystal structure.

    Efficient analysis of mammalian polysomes in cells and tissues using Ribo Mega-SEC

    Harunori Yoshikawa et al.
    Translationally active polysomes from mammalian cells/tissues are successfully separated with rapidity, high efficiency and exceptional reproducibility by a SEC-based approach, an accessible alternative to the conventional sucrose density gradient analysis.

    Transcription mediated insulation and interference direct gene cluster expression switches

    Tania Nguyen et al.
    The formation of mutually exclusive coding and non-coding transcription units contributes to transcriptional interference and insulation at gene clusters and manages state-switching in response to environmental change.

    Limits on information transduction through amplitude and frequency regulation of transcription factor activity

    Anders S Hansen, Erin K O'Shea
    The ability of cells to transmit information encoded in signaling dynamics is fundamentally limited by the gene decoding step.

    In-depth human plasma proteome analysis captures tissue proteins and transfer of protein variants across the placenta

    Maria Pernemalm et al.
    Comprehensive mass spectrometry analysis of human plasma proteome reveals tissue leakage proteins, describes variability between individual plasma proteomes and demonstrates protein transfer across the placenta during pregnancy.

    Stimulus salience determines defensive behaviors elicited by aversively conditioned serial compound auditory stimuli

    Sarah Hersman et al.
    Perceived imminence of threat and resulting intensity of defensive responses during serial compound stimulus conditioning are determined by auditory stimulus salience, not cue sequence as recently reported.

    Natural mismatch repair mutations mediate phenotypic diversity and drug resistance in Cryptococcus deuterogattii

    R Blake Billmyre et al.
    Eukaryotic pathogens, like Cryptococcus deuterogattii, can use elevated mutation rates to more rapidly adapt to stresses, such as drug challenges, but at the cost of lower fitness in less stressful environments.
