| Research Abstract |
We found MEK sumoylation strongly attenuated its kinase activity and inhibited the ERK pathway by disrupting the specific docking interaction between MEK and ERK. Interestingly, the Ras oncogene inhibited MEK sumoylation, and forced enhancement of MEK sumoylation suppressed Ras-induced cell transformation. These data indicates that the ablation of MEKsumoylation by the specific oncogene contributes to carcinogenesis.
