Abstract

We have investigated the agonists that activate transfected extracellular signal-regulated kinase 8 (ERK8) in cells, and have found that the most potent activators are hydrogen peroxide, DNA alkylating and cross-linking agents and the poly (ADP-ribose) polymerase inhibitor KU-0058948. The feature shared by all these agents is that they lead to the accumulation of single strand breaks in DNA, suggesting a role for ERK8 in the response to, or repair of, DNA single strand breaks. The DNA alkylating agent MMS also induced the disappearance of endogenous ERK8 by a proteasome-dependent mechanism.
