N2 - The phosphoprotein dishevelled (Dvl) is an integral part of Wnt signaling and has recently been shown to interact with the multifunctional scaffolding protein beta-arrestin. MEFs lacking beta-arrestins were able to phosphorylate Lrp6 in response to Wnt-3a, but decreased the activation of Dvl and blocked beta-catenin signaling. Furthermore, treatment of Xenopus laevis embryos with beta-arrestin morpholinos reduced the activation of endogenous beta-catenin, decreased the expression of the beta-catenin target gene, Xnr3, and blocked axis duplication induced by X-Wnt-8, and other molecules. Thus, our results identify beta-arrestin as a necessary component for Wnt/ beta-catenin signaling.
