Wnt binds to the Fz receptor and LRP5/6 co-receptor. This activates Dvl to cause the dissociation of Axin from the destruction complex, causing β-catenin to be stabilized and enter the nucleus.

Figure 6: The mechanism by which WNTs prevent the GSK3-catalysed phosphorylation of axin, APC and β-catenin ... signalling without triggering the WNT signalling pathway. If such drugs can ...
