Retraction of: J. Cell Sci. 121, 3468-3475.

The authors wish to retract the above paper. We have recently identified errors affecting certain figure panels in Fig. 5 in which control data were processed inappropriately such that the figure panels do not accurately report the original data. The misuse and re-use of western blot bands violates the editorial policy of Journal of Cell Science, and so we must retract this article. A. G. regrets the inappropriate figure manipulations, of which his co-author was completely unaware.

We sincerely apologize to the scientific community for any confusion or adverse consequences resulting from the publication of these data.
