MAP Kinase Phosphatase 3 (MKP3) Interacts with and Is Phosphorylated by Protein Kinase CK2α

Abstract

Mitogen-activated protein (MAP) kinases play a central role in controlling a wide range of cellular functions following their activation by a variety of extracellular stimuli. MAP kinase phosphatases (MKPs) represent a subfamily of dual specificity phosphatases, which negatively regulate MAP kinases. Although ERK2 activity is regulated by its phosphorylation state, MKP3 is regulated by physical interaction with ERK2, independent of its enzymatic activity (Camps, M., Nichols, A., Gillieron, C., Antonsson, B., Muda, M., Chabert, C., Boschert, U., and Arkinstall, S., (1998) Science 280, 1262–1265; Farooq, A., Chaturvedi, G., Mujtaba, S., Plotnikova, O., Zeng, L., Dhalluin, C., Ashton, R., and Zhou, M.

The interaction of ERK2 and MKP3 allows of their MKP3 a kinase a MKP3 and protein kinase a protein which The activity of MKP3 is in in ERK2 is and a of by Mitogen-activated protein (MAP) kinases play a central role in controlling a wide range of cellular functions following their activation by a variety of extracellular stimuli.
