    Wnt proteins can direct planar cell polarity in vertebrate ectoderm

    Chih-Wen Chu, Sergei Y Sokol
    Vertebrate early ectoderm displays planar polarity manifested by a fluorescent sensor and this polarity can be instructed by Wnt ligands.

    Embryonic attenuated Wnt/β-catenin signaling defines niche location and long-term stem cell fate in hair follicle

    Zijian Xu et al.
    Long-term hair follicle stem cells arise by embryonic progenitor cells occupying a niche location that is defined by attenuated Wnt/β-catenin signal.

    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.

    Constitutive scaffolding of multiple Wnt enhanceosome components by Legless/BCL9

    Laurens M van Tienen et al.
    BCL9/Legless is an integral component of the Wnt enhanceosome, harboring binding sites in its conserved C-terminus for multiple core components of this complex including ChiLS and Groucho/TLE.

    Structural basis of GSK-3 inhibition by N-terminal phosphorylation and by the Wnt receptor LRP6

    Jennifer L Stamos et al.
    Phosphorylation of the Wnt receptor LRP6 directly inhibits glycogen synthase kinase-3 by acting as a pseudosubstrate that stabilizes an active conformation of the enzyme, identical to autoinhibition by phosphorylation of its N terminus.

    R-spondins can potentiate WNT signaling without LGRs

    Andres M Lebensohn, Rajat Rohatgi
    R-spondins 2 and 3 can potentiate WNT signaling in the absence of LGRs through interactions with ZNRF3/RNF43 E3 ubiquitin ligases and heparan sulfate proteoglycans, defining two alternative modes of R-spondin-mediated signaling.
