This all-new edition of a classic text has been thoroughly revised to keep pace with the rapid progress in signal transduction research. With didactic skill and clarity, the author relates the observed biological phenomena to the underlying biochemical processes.Directed at advanced students, teachers, and researchers in biochemistry and molecular biology, this book describes the molecular basis of signal transduction, regulated gene expression, the cell cycle, tumorigenesis and apoptosis.From the reviews of the previous edition:"Provides a comprehensive account of cell signaling and signal transduction and, where possible, explains these processes at the molecular level" (Angewandte Chemie)"The clear and didactic presentation makes it a textbook very useful for students and researchers not familiar with all aspects of cell regulation. (Biochemistry)"This book is actually two books: Regulation and Signal Transduction. (Drug Research)"
