BCAS2 interacts with β-catenin. (A–C) Flag-tagged β-catenin was co-transfected with or without HA-tagged BCAS2 into HEK293T cells. Cell lysates were immunoprecipitated using anti-Flag antibody. Eluted proteins were analyzed by western blotting using indicated antibodies. In (C), for Wnt signaling activation, cells were treated with Wnt3a CM for 5 h before harvest. (D, E) YN-BCAS2 and YC-β-catenin were either individually or collectively transfected into HeLa cells. The expression of YN-BCAS2 and YC-β-catenin was analyzed with anti-GFP antibody (D). The reconstituted YFP fluorescence in living cells was detected by confocal laser scanning microscopy with excitation at 488 nm (E). (F) Schematics of full-length and deletion mutants of β-catenin. (G) HEK293T cells were transfected with HA-tagged BCAS2 and Flag-tagged deletion mutants of β-catenin. Cell lysates were then immunoprecipitated using anti-Flag antibody followed by western blot analysis. (H) GST pull-down assays were performed using bacterially expressed GST, GST-ARM1-12, and His-BCAS2. Scale bars, 10 μm (D, E). |
