There was an error published in J. Cell Sci. 125, 5288-5301.In Fig. 2B, panels labelled as the actin input and p120-catenin IP:p120-catenin panels were inadvertently assembled to show the same blots. Concerns were also raised about possible duplications and/or splices in Figs 4A, 4E, 5D, 6A and 6C. The authors were unable to obtain the original data in order to address these concerns and therefore repeated the experiments. The new data are shown in the figures below and have been verified by the corresponding author's institute as supporting the original conclusions of the study. There are no changes to the figure legends, which are accurate.The authors acknowledge the increased contribution of Beatriz Del Valle-Pérez in repeating the experiments and apologise to the readers for any confusion that these errors might have caused. Fig. 2. Wnt-induced Rac1 activation is dependent on Vav2 interaction with p120-catenin. Vav2 (A) and p120-catenin (B) were immunoprecipitated from 500 µg SW-480 whole-cell extracts treated with control or Wnt3a-conditioned medium for the times indicated. Protein complexes were analyzed by western blot (WB) with anti-p120-catenin, anti-Vav2, anti-E-cadherin and anti-Rac1. 10 µg of SW-480 whole-cell extracts were included as internal reference (input). The graphs on the right are autoradiograms from four different experiments that were quantified and the mean ± s.d. obtained after 2 hours of incubation with Wnt3a medium. Each value is presented relative to that obtained in cells treated with control medium and normalized with respect to the amount of immunoprecipitated Vav2 or p120-catenin. (C) SW-480 cells stably expressing scrambled or shRNA specific for Vav2 were treated with control or Wnt3a-conditioned medium for 2 hours. GST-PAK pull-down assays were performed and active Rac1 was determined by WB. Autoradiograms from five different experiments performed in triplicate were quantified and the mean ± s.d. was obtained for each condition. Each value is presented relative to that obtained in nondepleted cells treated with control medium. (D) Cytosolic and nuclear lysates were obtained from control and Vav2-depleted SW-480 cells treated with control or Wnt3a-conditioned medium for 15 hours. β-catenin distribution between the two cell compartments was analyzed by WB. 2120© 2016.

The nuclear fraction was separated from the cytosolic and membrane-associated fraction as detailed in Materials and Methods. β-catenin levels in each cellular fraction were analyzed by WB. Lamin-β1 was used as a nuclear marker and pyruvate kinase as a marker for the cytosolic-plus-membrane fraction. In the right panel of C, p120-catenin wt, Y112E and Y217E...

There was an error published in J. Cell Sci. 124, 2298-2309.Some of the blots presented in Fig. 4A were inadvertently duplicated in Fig. 6D. The blots in Fig. 4A are correct as presented. The correct Fig. 6 is presented below. There are no changes to the figure legend, which is accurate. This error does not affect the conclusions of the study.The authors apologise to the readers for any confusion that this error might have caused. . Kaiso also interacts with β-catenin and its binding is regulated by p120-catenin. (A) 2 pmol of recombinant GST-Kaiso or GST as a control was incubated with 1 pmol of full-length β-catenin or two deletion mutants comprising armadillo repeats 1-12 (amino acids 120-683) or 1-6 (amino acids 120-420). Protein complexes were affinity purified with glutathione-Sepharose and analyzed by western blotting (WB) with anti-β-catenin antibody. Blots were re-analyzed with anti-GST antibody to ensure that a similar amount of fusion protein was present. (B) 2 pmol of recombinant GST-Kaiso, or GST as a control, was incubated with 2 pmol of p120-catenin (amino acids 102-911) (left-hand panel) or 2 pmol of full-length β-catenin (right-hand panel). Protein complexes were affinity purified with glutathione-Sepharose and analyzed by western blotting with the indicated antibodies. 'St' indicates the signal obtained with known amounts of recombinant proteins used as control. (C) Pull-down assays were performed by incubating 7 pmol of GST-Kaiso with 400 μg of whole-cell extracts from SW-480 cells transfected with pcDNA3-Tcf-4-HA. When indicated, 35 pmols of p120-catenin or β-catenin was added to the incubation medium. Protein complexes were affinity purified and analyzed by western blotting with the indicated antibodies. (D) SW-480 cells were infected with scrambled shRNA (Ctl) or shRNA specific for p120-catenin, and were treated with control or Wnt3a-conditioned medium for 6 hours. Kaiso was immunoprecipitated (IP) and immunocomplexes were analyzed by western blotting. (E) SW480 cells were treated with control or Wnt3a-conditioned medium for 6 hours. β-catenin was immunoprecipitated from SW-480 total cell extracts and the immunocomplex was analyzed by western blotting. In the input lane, 5% of each total cell extract used is shown. (F) Kaiso was immunoprecipitated with a specific antibody from total cell extracts of HT29-M6 cells treated with control or Wnt3a-conditioned medium for 6 hours. Associated proteins were analyzed by western blotting. All the data presented in this figure are representative of at least three independent experiments.
