    Shade-induced nuclear localization of PIF7 is regulated by phosphorylation and 14-3-3 proteins in Arabidopsis

    Xu Huang et al.
    A phosphorylation dependent translocation of PIF7 and involvement of 14-3-3 proteins reveal novel regulation mechanisms in shade signal transduction.

    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.

    T-box3 is a ciliary protein and regulates stability of the Gli3 transcription factor to control digit number

    Uchenna Emechebe et al.
    The transcription and splicing factor T-box3 is present in primary cilia, regulates multiple aspects of limb development, and interacts with members of the protein complex required for the stability and processing of the Gli3 transcription factor.

    Linking traits based on their shared molecular mechanisms

    Yael Oren et al.
    Systematic analysis of a broad spectrum of behavioral and physiological traits reveals novel relationships among complex traits, and resolves their underlying combination of genetic loci and molecular mechanisms.

    Memory CD4 T cell subsets are kinetically heterogeneous and replenished from naive T cells at high levels

    Graeme Gossel et al.
    The maintenance of memory CD4 T cells in mice relies on a continual and strikingly high level of replenishment from naive precursors, and older memory T cells may resist the influx of newer ones.

    Latrophilin-2 and latrophilin-3 are redundantly essential for parallel-fiber synapse function in cerebellum

    Roger Shen Zhang et al.
    Knockout of both latrophilin-2 and latrophilin-3 from Purkinje cells in mice selectively impairs parallel-fiber synapses, revealing a redundant but critical function for latrophilins at specific synapses.

    BLOS1 mediates kinesin switch during endosomal recycling of LDL receptor

    Chang Zhang et al.
    BLOS1 is a new regulator of LDLR endosomal recycling through coordinating kinesins during long-range transport, and depletion of BLOS1 in mouse liver leads to aberrant lipid metabolism.

    The pro-regenerative effects of hyperIL6 in drug-induced liver injury are unexpectedly due to competitive inhibition of IL11 signaling

    Jinrui Dong et al.
    IL6ST (gp130) binding proteins, such as HyperIL6, promote liver regrowth in a STAT3-indpependent manner through competitive inhibition of anti-regenerative IL11 signaling.

    High-resolution structures of kinesin on microtubules provide a basis for nucleotide-gated force-generation

    Zhiguo Shang et al.
    Microtubule attachment fundamentally modifies kinesin's behavior by triggering a ‘clamshell’ opening of the nucleotide cleft, subsequently reversed by ATP binding, that couples to cargo translocation.

    The nucleolar protein NIFK promotes cancer progression via CK1α/β-catenin in metastasis and Ki-67-dependent cell proliferation

    Tsung-Chieh Lin et al.
    NIFK promotes lung cancer metastasis via Runx1-dependent repression of CK1α, which activates TCF4/β-catenin signaling.
