Kinase-active RAF1 leads to the phosphorylation of MAP2K1 on S222. 2 / 2
2 |

"To address a possible role of mutant C-RAF proteins in the constitutive phosphorylation of ERK1/2, kinase assays were done with Myc-tagged C-RAF proteins immunoprecipitated from transiently transfected Cos-7 cells. Strong constitutive kinase activity was shown for S427GC-RAF whereas I448VC-RAF did not significantly differ from wt C-RAF (Fig. 3A)."

"Raf-1 activity, measured by the abundance of phosphorylated S217/221 MEK1 2, a direct target of Raf-1 (30) , was consistently elevated in Cdc37 overexpressing cells, whereas total MEK1 2 levels were unchanged."
