Abstract:
Nearly all cell surface receptors utilize one or more of the mitogen-activated protein kinase cascades in their repertoire of signal transduction mechanisms. Recent advances in the study of such cascades include the cloning of genes encoding novel members of the cascades, further definition of the roles of the cascades in responses to extracellular signals, and examination of cross-talk between different cascades.
