Retraction of: J. Cell Sci. 121, 1373-1382.

The authors wish to retract this paper after it has come to their attention that the two constructs that they thought were encoding for β-catenin or stabilized β-catenin are, in fact, expressing an unrelated protein. This was discovered when both constructs were used as part of another study, and it became clear that they had been confused with an unrelated construct from another project that does not express β-catenin or stabilized β-catenin.

The authors apologize for not having detected the error prior to publication.
