    Helix breaking transition in the S4 of HCN channel is critical for hyperpolarization-dependent gating

    Marina A Kasimova et al.
    The gating polarity of a voltage-gated ion channel is primarily determined by turn propensity of residues at a critical position in the middle of the S4 voltage-sensing helix.

    High resolution cryo-EM structure of the helical RNA-bound Hantaan virus nucleocapsid reveals its assembly mechanisms

    Benoît Arragain et al.
    Hantaan virus nucleocapsid cryo-EM structure determined at 3.3 Å resolution reveals how nucleoproteins assemble into a metastable helix containing a continuous RNA-binding groove compatible with genome encapsidation and compaction.

    Immune genes are hotspots of shared positive selection across birds and mammals

    Allison J Shultz, Timothy B Sackton
    Pathogens, particularly viruses, target the same genes over deep evolutionary time, resulting in shared signatures of positive selection and transcriptional responses at the same genes.

    Mouse TRPA1 function and membrane localization are modulated by direct interactions with cholesterol

    Justyna B Startek et al.
    The activation and membrane localization of the broadly-tuned noxious chemosensory cation channel TRPA1 are regulated by direct interactions with cholesterol via CRAC motifs in transmembane segments 2 and 4.

    The retromer complex safeguards against neural progenitor-derived tumorigenesis by regulating Notch receptor trafficking

    Bo Li et al.
    The retromer complex serves as a bomb squad to retrieve and disarm the potentially harmful pool of Notch receptors in a timely manner and thereby safeguards against brain tumor formation.

    Deletion of KCNQ2/3 potassium channels from PV+ interneurons leads to homeostatic potentiation of excitatory transmission

    Heun Soh et al.
    Loss of potassium channel activity from fast-spiking interneurons increases their excitability leading to unexpectedly increased fast excitatory transmission and seizure susceptibility.
