On page 835, the western blot at the bottom of Figure 5B is a duplicate copy of the western blot at the bottom of Figure 5C.In the description of Figure 5B in the figure legend, "Lane 8: expression control for FBXW7, lysate from FBXW7 transfected cells, no-CoIP" should read "Lane 8: lysate from untransfected cells, no-CoIP."The authors have inserted the correct blot at the bottom of Figure 5B, and the corrected Figure 5 and legend are shown below.This error does not affect the results or the conclusions of the study.
