    Non-canonical Wnt signaling regulates junctional mechanocoupling during angiogenic collective cell migration

    Joana R Carvalho et al.
    Analysis of axial polarity distributions shows that Wnt5a regulates collective cell migration in vivo by stabilizing vinculin at adherens junctions and fine-tuning mechanocoupling between neighbouring cells.

    Structure and functional properties of Norrin mimic Wnt for signalling with Frizzled4, Lrp5/6, and proteoglycan

    Tao-Hsin Chang et al.
    The crystal structure of Norrie Disease Protein in complex with the extracellular cysteine-rich domain of Frizzled4 receptor and sucrose octasulfate reveals binding sites for Frizzled4, low density lipoprotein receptor related protein 5/6, and proteoglycan.

    Restraint of presynaptic protein levels by Wnd/DLK signaling mediates synaptic defects associated with the kinesin-3 motor Unc-104

    Jiaxing Li et al.
    Synaptic defects previously attributed to loss of kinesin function are found to be mediated by the Wnd/DLK axonal injury signaling pathway, which restrains the total levels of presynaptic proteins in response to their accumulation.

    Daple is a novel non-receptor GEF required for trimeric G protein activation in Wnt signaling

    Nicolas Aznar et al.
    Daple is a guanine nucleotide-exchange factor (GEF) for trimeric G proteins that enables Wnt/Frizzled receptors to transactivate G proteins during non-canonical Wnt signaling.

    Dkk2 promotes neural crest specification by activating Wnt/β-catenin signaling in a GSK3β independent manner

    Arun Devotta et al.
    Dkk2, a member of the Dikkopf family of Wnt antagonists, acts as a positive regulator of Wnt signaling during neural crest formation.

    R-spondins engage heparan sulfate proteoglycans to potentiate WNT signaling

    Ramin Dubey et al.
    Heparan Sulfate Proteoglycans function as receptors for the R-spondins, a family of growth factors that amplify the strength of WNT signaling during development and in adult stem cells.

    Conformational change of Dishevelled plays a key regulatory role in the Wnt signaling pathways

    Ho-Jin Lee et al.
    The ligand-binding pocket of the Dishevelled PDZ domain can be occupied by Dishevelled's own highly conserved C-terminus, inducing a closed conformation that is ‘opened’ when Wnt signaling stimulates interaction between Frizzled and Dishevelled.

    Wnt/β-catenin regulates an ancient signaling network during zebrafish scale development

    Andrew J Aman et al.
    Zebrafish scales depend on interactions among Wnt, Ectodysplasin and Hedgehog signaling pathways similar to those underlying feathers, teeth and hair follicles, suggesting a deep homology of ectodermal appendages in vertebrates.

    Limited dishevelled/Axin oligomerization determines efficiency of Wnt/β-catenin signal transduction

    Wei Kan et al.
    In vitro and in cellulo characterization of oligomerization by the cytoplasmic Wnt effector dishevelled and its partner Axin provide new mechanistic principles for Wnt/β-catenin signaling.

    Genome-wide interrogation of extracellular vesicle biology using barcoded miRNAs

    Albert Lu et al.
    A screen using artificially barcoded, exosomal microRNAs, paired with CRISPR guide RNAs, helped identify new players in multivesicular endosome exocytosis and a role for Wnt signaling.
