    Somatosensory neurons integrate the geometry of skin deformation and mechanotransduction channels to shape touch sensing

    Alessandro Sanzeni et al.
    Nonlinear elasticity of skin tissues and somatosensory neural responses are combined to predict and test C. elegans processing of touch stimuli and modifications due to changes in the body mechanics.

    Structure-based membrane dome mechanism for Piezo mechanosensitivity

    Yusong R Guo, Roderick MacKinnon
    Mechanosensitive Piezo channel induces local membrane curvature to mediate mechanical gating.

    Establishment and maintenance of heritable chromatin structure during early Drosophila embryogenesis

    Shelby A Blythe, Eric F Wieschaus
    The patterns of chromatin architecture that underlie the initial embryonic cell fate decisions are established during a period of intense cell cycle activity, and these patterns are stably maintained even in highly condensed mitotic chromatin.

    Evidence for additive and synergistic action of mammalian enhancers during cell fate determination

    Jinmi Choi et al.
    Temporal changes in genome-wide enhancer transcription activity during a transdifferentiation event reveal additive and synergistic enhancer cooperation.

    Global alignment and assessment of TRP channel transmembrane domain structures to explore functional mechanisms

    Katherine E Huffer et al.
    Structure-based alignment of TRP channels enables comparison of structural changes, ion permeation pathways and ligand-binding sites and reveals over-representation of structures that represent non-conducting states.

    Clusters of cooperative ion channels enable a membrane-potential-based mechanism for short-term memory

    Paul Pfeiffer et al.
    Independently gating ion channels typically act fast within milliseconds, but cooperative interactions within a cluster of channels allow for a memory of previous electrical activity for several seconds.

    Folding behavior of a T-shaped, ribosome-binding translation enhancer implicated in a wide-spread conformational switch

    My-Tra Le et al.
    Folding and unfolding pathways are described for a ribosome-binding 3' cap-independent translation enhancer at the center of a conformational rearrangement that is implicated in the transition from translation to replication of an RNA virus.

    TRAIN (Transcription of Repeats Activates INterferon) in response to chromatin destabilization induced by small molecules in mammalian cells

    Katerina Leonova et al.
    Type I interferon signaling protects cells from the loss of epigenetic integrity, since it is activated in cells in response to accumulation of transcripts originating from normally silenced heterochromatin, caused by small-molecule-mediated nucleosome unfolding.

    HIV-1 Env trimer opens through an asymmetric intermediate in which individual protomers adopt distinct conformations

    Xiaochu Ma et al.
    The identification of a single-CD4 bound asymmetric HIV-1 Envelope trimer intermediate provides new mechanistic insights into the activation of Envelope for fusion, and highlights the importance of asymmetry in biology.

    Quantitative regulation of the dynamic steady state of actin networks

    Angelika Manhart et al.
    Cells are able to control the actin network length and steering by adjusting geometric, structural, or biochemical parameters such as ADF/Cofilin and actin concentrations, and network width.
