To improve our understanding of the molecular mechanisms by which LRP5 triggers the canonical Wnt signaling cascade, we have screened for potential partners of LRP5 using the yeast two-hybrid system and identified Frat1 as a protein interacting with the cytoplasmic domain of LRP5. We demonstrate here that LRP5/Frat1 interaction is involved in beta-catenin nuclear translocation and TCF-1 transcriptional activation. The addition of Wnt3a or overexpression of constitutively active truncated LRP5 (LRP5C) induces Frat1 recruitment to the cell membrane. Overexpression of a dominant negative form of disheveled (Dvl) shows that this protein positively affects LRP5/Frat1 interaction. Furthermore, the fact that dominant negative Dvl does not interfere with LRP5C/Frat1 interaction can explain how LRP5C is capable of acting independently of this major Wnt signaling player. Axin, which has been shown to interact with LRP5 and to be recruited to the membrane through this interaction, was found to co-immunoprecipitate with Frat1 and LRP5. We propose that recruitment of Axin and Frat1 to the membrane by LRP5 leads to both Axin degradation and Frat1-mediated inhibition of glycogen synthase kinase-3. As a consequence, beta-catenin is no longer bound to Axin or phosphorylated by glycogen synthase kinase-3, resulting in TCF-1 activation."xsd:string |
