Ctbp2 associates with the β-catenin destruction complex in ESCs. (a) Using mass spectrometry,³⁵ we identified Ctbp2-interacting proteins that were β-catenin and core β-catenin destruction components in ESCs with reasonable peptide counts. (b) Using immunoprecipitation with Flag antibodies from ESCs, showing that Flag-tagged CTBP2 was stably incorporated, and endogenous β-catenin, Gsk-3β and Apc were detected with the indicated antibodies. (c) Using immunoprecipitation with Ctbp2 antibodies from wild-type ESCs, endogenous β-catenin was detected with the indicated antibodies.
