Erratum for the Report “Phosphorylation-dependent ubiquitination of cyclin E by the SCFFbw7 ubiquitin ligase” by D. M. Koepp et al.
In Fig. 1B of the Report “Phosphorylation-dependent ubiquitination of cyclin E by the SCFFbw7 ubiquitin ligase” (5 October 2001, p. 173), an image of the positive controls showing ubiquitination of cyclin E/Cdk2 in lanes 10, 11, and 12 was mistakenly used in the positive control lanes 4, 5, and 6 during figure assembly. Both experiments were performed under identical conditions. The cognate positive control lanes that correctly correspond to the experimental lanes 7, 8, and 9 are now shown in the revised figure. The conclusions drawn from this figure and the paper itself are not altered by this error.
