Phosphorylated WWTR1 (TAZ) and DVL interact to form a complex in the cytosol. Thus sequestered, DVL2 is unable to undergo phosphorylation by casein kinase, inhibiting its role in WNT signaling. WWTR1 - DLV interaction thus appears to link the Hippo and WNT signaling processes (Varelas et al. 2010). The stoichiometry of the WWTR1:DVL complex is unknown.
