Mitogen-activated protein kinase kinase.
based on mapping to UniProt Q02750
ATP + a protein = ADP + a phosphoprotein.
-!- A dual-specific protein kinase and requires mitogen-activated protein kinase kinase kinase (MAPKKK) for activation. -!- It is required for activation of EC 2.7.11.24. -!- Phosphorylation of MEK1 by Raf involves phosphorylation of two serine residues. -!- Mitogen-activated protein kinase (MAPK) signal transduction pathways are among the most widespread mechanisms of cellular regulation. -!- Mammalian MAPK pathways can be recruited by a wide variety of stimuli including hormones (e.g. insulin and growth hormone), mitogens (e.g. epidermal growth factor and platelet-derived growth factor), vasoactive peptides (e.g. angiotensin-II and endothelin), inflammatory cytokines of the tumor necrosis factor (TNF) family and environmental stresses such as osmotic shock, ionizing radiation and ischemeic injury.
