Target Information

ERK1 and ERK2 are widely expressed and are involved in the regulation of meiosis, mitosis, and postmitotic functions in differentiated cells.
Many different stimuli, including growth factors, cytokines, virus infection, ligands for heterotrimeric G protein–coupled receptors, and transforming agents, activate the ERK1 and ERK2 pathways.
When growth factors bind to the receptor tyrosine kinase, Ras interacts with Raf, the serine/threonine protein kinase, and activates it as well. Once activated, Raf phosphorylates serine residues in two further kinases, MEK1/2, which in turn phosphorylate tyrosine/threonine residues in extracellular-signal regulated kinase (ERK) 1/2.
Upon activation, the ERKs either phosphorylate a number of cytoplasmic targets or migrate to the nucleus, where they phosphorylate and activate transcription factors such as c-Fos and Elk-1.
