Since publication of our article [1] we have noticed that an error was introduced during the assembly of Fig. 1d (Fig. 1 here), resulting in the duplication of two panels. Specifically, lanes 7–12 probed for TIA-1 are the same as lanes 13–18 also probed for TIA-1. In addition, lanes 7–12 probed with Actin are the same as lanes 19–24 probed with Actin [1]. We sincerely regret this error. The corrected figure appears below.
