Retraction of: J. Cell Sci. 120, 3045–3052.

After it was brought to our attention by the Journal of Cell Science, careful examination of the above paper published in the journal in 2007 highlighted some errors we made related to the re-use of our previously published western blot bands in parts A, B and C of Figure 3, and duplication of western blot bands in Figures 3A and 4A. The misuse and re-use of western blot bands violated the editorial policy of Journal of Cell Science, and so we must retract this article.

The errors originated in Dr Zhiguo Wang's laboratory at the Montreal Heart Institute. Dr Wang takes full responsibility and apologises to the editors and readership of Journal of Cell Science for any inconvenience caused and any negative impact this might have on the journal.
