    Time-resolved multimodal analysis of Src Homology 2 (SH2) domain binding in signaling by receptor tyrosine kinases

    Joshua A Jadwin et al.
    The recruitment of SH2-containing proteins to Epidermal Growth Factor in cells happens more slowly than predicted by in vitro techniques.

    Switch-like Arp2/3 activation upon WASP and WIP recruitment to an apparent threshold level by multivalent linker proteins in vivo

    Yidi Sun et al.
    Intersectin counterparts in yeast recruit WASP and WIP to endocytic sites to establish a robust multivalent SH3 domain-PRM interaction network which gives actin assembly onset a switch-like behavior in vivo.

    A novel SH2 recognition mechanism recruits Spt6 to the doubly phosphorylated RNA polymerase II linker at sites of transcription

    Matthew A Sdano et al.
    The tandem SH2 domains of Spt6 use novel mechanisms to bind unexpected phosphorylated serine and threonine residues in the RNA polymerase II linker to recruit Spt6 to sites of transcription and maintain repressive chromatin.

    The novel SH3 domain protein Dlish/CG10933 mediates fat signaling in Drosophila by binding and regulating Dachs

    Yifei Zhang et al.
    The Fat-regulated scaffolding protein Dlish controls the activity, levels and cortical localization of Warts-inhibiting myosin Dachs by linking Dachs to a critical Dachs regulator, the DHHC palmitoyltransferase Approximated, and to the Fat-mediated regulation of Dachs stability.

    Gating mechanisms during actin filament elongation by formins

    Fikret Aydin et al.
    Formins slow elongation of actin filament by either sterically blocking the addition of actin subunits or flattening the helical twist of the filament end.

    Allosteric regulators selectively prevent Ca2+-feedback of CaV and NaV channels

    Jacqueline Niu et al.
    Two structurally-unrelated regulatory proteins utilize parallel molecular mechanisms to selectively tune calcium and calmodulin feedback of calcium and sodium ion channels and reveals a novel strategy to engineer synthetic channel modulators.

    Point of View: Data science for the scientific life cycle

    Daphne Ezer, Kirstie Whitaker
    Each stage of the scientific life cycle stands to benefit from the introduction of data science techniques.
  1. Meta-Research: How significant are the public dimensions of faculty work in review, promotion and tenure documents?

    Juan P Alperin et al.
    An analysis of review, promotion and tenure documents from 129 US and Canadian universities suggests institutions could better fulfill their public missions by changing how they incentivize the public dimensions of faculty work.
