MAP (mitogen-activated protein) kinases are ubiquitous serine/threonine kinases that are activated by a wide variety of extracellular signals. The MAP kinase cascade plays a crucial role in signal transduction from the membrane to the nucleus and appears to be highly conserved throughout evolution. In mammalian cells, this cascade is activated by both tyrosine kinase receptors and G-protein coupled receptors. MAP kinase activation, an essential step in triggering cell cycle progression, leads to changes in properties of cytoplasmic, membrane-associated and nuclear proteins. A unique feature of MAP kinases is that their full activation requires phosphorylation of both a threonine residue and a tyrosine residue which are separated by a single amino acid. This phosphorylation is brought about by the action of MAP kinase kinase (MEK), a dual specificity kinase. Once activated, MAP kinase relays signals downstream by phosphorylating various other protein kinases and regulatory proteins. Following activation, MAP kinases translocate from the cytosol into the nucleus and phosphorylate a number of transcription factors leading to changes in gene expression. Supplied with a data sheet.
