Two cancer related proteins, tyrosine phosphatase PTPRK and ubiquitin ligase ZNRF3, interact to downregulate Wnt receptors, thereby regulating Spemann organizer function during Xenopus development.
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.

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.
A novel population of adipocytes that play essential roles in adaptive thermogenesis via cell autonomous and non-autonomous effects and regulate systemic glucose metabolism in mice.
Wnt/beta-catenin signaling is essential for the specification of dorsal cell fate in amphioxus, suggesting a common evolutionary origin for the formation of the dorsal organizer in chordates.

Mouse genetic approaches show that multiple Wnt endothelial sources orchestrate the spatiotemporal distribution of hepatocyte functions during liver maturation and respecify metabolic zonation during liver repair.
