Signaling by AMER1 mutants

AMER1/WTX is a component of the destruction complex that interacts directly with beta-catenin through its C-terminal half. Depletion of AMER1 through siRNA stabilizes cellular beta-catenin levels and increases transcriptional activity in a reporter assay consistent with a role for AMER1 in the degradation of beta-catenin (Major et al, 2007). Deletions of the entire AMER1 gene have been reported in Wilms tumor, as have nonsense and missense mutations that truncate the protein before the beta-catenin interaction domain. These mutations are predicted to stabilize beta-catenin and increase WNT signaling (reviewed in Saito-Diaz et al, 2013; Huff, 2011).
