title: Parallel signal processing among mammalian MAPKs.
abstract: The intracellular signalling field is dominated by the mitogen-activated protein kinase (MAPK) cascade and its control, which involves the small GTPase Ras and sequential kinase activation. Until recently, ERK1 and ERK2 were the only cloned and well-characterized mammalian MAPKs; diverse ligand-stimulated, proline-directed protein phosphorylation events were attributed to these kinases. The recent discovery of two other MAPK subtypes, the JNK/SAPK subfamily and p38/RK (mammalian equivalents of HOG1 in yeast), reveals extreme complexity within the family and, most intriguingly, the existence in mammalian cells of parallel MAPK cascades that can be activated simultaneously.
