Mitogen-activated protein kinases (MAPKs) are common signal transducers in all eukaryotic organisms. MAPKs are activated by protein kinase cascades consisting of MAPK kinases (MAP2Ks) and MAPK kinase kinases (MAP3Ks). Extracellular-signal regulated kinases 1 and 2 (ERK1/2) are the best characterized MAPKs. Like other MAPKs their activity is regulated by dual phosphorylation as well as dephosphorylation by a host of phosphoprotein phosphatases. The ability to phosphorylate or thiophosphorylate ERK2 in vitro, as described here, is valuable for use in downstream applications designed to investigate MAPK signaling networks.
