beta-Arrestin Promotes Wnt-induced Low Density Lipoprotein Receptor-related Protein 6 (Lrp6) Phosphorylation via Increased Membrane Recruitment of Amer1 Protein
Original language description
beta-Arrestin is a scaffold protein that regulates signal transduction by seven transmembrane-spanning receptors. Among other functions it is also critically required for Wnt/beta-catenin signal transduction. In the present study we provide for the firsttime a mechanistic basis for the beta-arrestin function in Wnt/beta-catenin signaling. We demonstrate that beta-arrestin is required for efficient Wnt3a-induced Lrp6 phosphorylation, a key event in downstream signaling. beta-Arrestin regulates Lrp6 phosphorylation via a novel interaction with phosphatidylinositol 4,5-bisphosphate (PtdIns(4,5)P-2)-binding protein Amer1/WTX/Fam123b. Amer1 has been shown very recently to bridge Wnt-induced and Dishevelled-associated PtdIns(4,5)P-2 production to the phosphorylation of Lrp6. Using fluorescence recovery after photobleaching we show here that beta-arrestin is required for the Wnt3a-induced Amer1 membrane dynamics and downstream signaling.
