    Cell-autonomous regulation of epithelial cell quiescence by calcium channel Trpv6

    Yi Xin et al.
    Genetics, in vivo imaging, and unbiased chemical biology screens reveal that Trpv6 functions as a cellular quiescence regulator and delineates a Trpv6-mediated Ca2+ signaling pathway maintaining the quiescent state.

    Dopamine receptors reveal an essential role of IFT-B, KIF17, and Rab23 in delivering specific receptors to primary cilia

    Alison Leaf, Mark Von Zastrow
    The mechanism of signaling receptor delivery to primary cilia involves a specific cellular role of a Rab protein that is critical for vertebrate development.

    Wnt signaling-mediated redox regulation maintains the germ line stem cell differentiation niche

    Su Wang et al.
    Wnt signaling regulates cellular redox in the germline stem cell differentiation niche via a novel regulatory mechanism, thereby controlling germ line stem cell progeny differentiation.

    A chloroplast retrograde signal, 3’-phosphoadenosine 5’-phosphate, acts as a secondary messenger in abscisic acid signaling in stomatal closure and germination

    Wannarat Pornsiriwong et al.
    Molecular signals from chloroplasts can synergistically interact with the plant hormone, abscisic acid (ABA), to regulate non-canonical signaling pathways mediating fundamental cellular processes including stomatal closure, seed dormancy and germination.

    Two bifunctional inositol pyrophosphate kinases/phosphatases control plant phosphate homeostasis

    Jinsheng Zhu et al.
    Genetic and biochemical analysis of two enzymes reveals that inositol pyrophosphate signaling molecules allow plants to sense and regulate cellular phosphate levels, and to take up more phosphate when needed.

    All-atom molecular dynamics of the HBV capsid reveals insights into biological function and cryo-EM resolution limits

    Jodi A Hadden et al.
    All-atom molecular dynamics of the HBV capsid supports a role for structural asymmetry in biological function, reveals the potential for triangular pores to mediate cellular signaling, and indicates that capsid flexibility may limit resolution attainable by cryo-EM.

    Structure and mechanism of a Hypr GGDEF enzyme that activates cGAMP signaling to control extracellular metal respiration

    Zachary F Hallberg et al.
    A newfound signaling enzyme that diverged from a protein family ubiquitous in bacteria provides mechanistic insights into how new signaling activity emerges to control distinct cellular function and physiology.

    Distributing tasks via multiple input pathways increases cellular survival in stress

    Alejandro A Granados et al.
    Single-cell experiments and mathematical modelling show that cellular signalling networks are vulnerable to trade-offs in speed versus accuracy, but that these vulnerabilities can be overcome by distributing the two tasks to different, although interacting, subnetworks.
