Allegations of image manipulation were made for Fig.1A and Fig. 2E,F on PubPeer. As the data were obtained for these figures 20 years ago, the authors no longer have all of the original images and blots. A cropped blot was found for data shown in Fig. 2E, but the resolution was poor and no definitive conclusion on any band duplication could be made.

The authors have no explanation for how these issues could have arisen and say that although these issues do not modify the scientific message, they are retracting the paper. They apologise to readers for any inconvenience.
