The Editors have retracted this article because of concerns regarding the figures. Specifically, there appears to be overlap between Figure 1C, D, actin controls have been reused in Figures 2C, 4D and 5A, and Fig. 7C appears to be replicated from Fig. 6C of a different article by the same group of authors reporting a different experiment [1]. In addition, there is a concern that the quantifications in this article and [1], e.g. between the histograms in Fig. 1B, C and D in this article and in Fig. 1B, C and D in [1], have very different values for identical experiments, and also have very small standard deviations.

The Editors therefore no longer have confidence in the accuracy of the reported data and the conclusions of the article.
