This article has been withdrawn by the authors. Lanes 1–4 and lanes 7–10 of the G-JNK immunoblot in Fig. 1B were duplicated. In Fig. 2A, the DP-JNK immunoblots on the left were inappropriately manipulated. In Fig. 2A, the G-JNK immunoblots in the middle row were duplicated. In Fig. 3B, lanes 2 and 7 of the phosphorylated MBP panel were duplicated. In Fig. 5A, lane 1 of the Ras-GTP panel was inappropriately manipulated. Lanes 7 and 11 were duplicated. Because the original data are no longer available, in the interest of maintaining accuracy in the published scientific literature, the authors wish to withdraw this article. However, the authors have full confidence in the findings and conclusions of this paper.
