Scientific Background: MEK1 (MAP2K1) is a Dual specificity protein kinase of the STE group and STE7 family. It functions in the MAP kinase signalling pathway, and plays a role in the regulation of cell growth, adhesion, survival, and differentiation. Dual specificity protein kinase which acts as an essential component of the MAP kinase signal transduction pathway. Binding of extracellular ligands such as growth factors, cytokines and hormones to their cell-surface receptors activates Ras and this initiates Raf1 activation. Raf1 then further activates the dual-specificity protein kinases MAP2K1/MEK1 and MAP2K2/MEK2. Both MAP2K1/MEK1 and MAP2K2/MEK2 function specifically in the MAPK/ERK cascade, and catalyze the concomitant phosphorylation of a threonine and a tyrosine residue in a Thr-Glu-Tyr sequence located in the extracellular signal-regulated kinases MAPK3/ERK1 and MAPK1/ERK2, leading to their activation and further transduction of the signal within the MAPK/ERK cascade. Phosphorylation of S212 and T286 in MEK1 inhibits phosphotransferase activity, and phosphorylation at T292 increases molecular association with ERK2 and Raf1, but reduces interaction with ERK1. Phosphorylation of T386 induces interaction with ERK2.
