_Nature_ 446, 690–694 (2007) It has come to our attention that some of the control lanes in Fig. 2a (_Kai1_ and _Mkk4_ control lanes) may have been inadvertently duplicated during figure

assembly; the other control lanes and the experimental _Maspin_ lanes are correct. We have therefore repeated the experiments and obtained the same results as those in the published figure.
