This comprehensive volume focuses on the ways in which synthetic peptides have been exploited in order to expand our understanding of the molecular mechanisms involved in protein phosphorylation. It recognizes that virtually all physiological processes are regulated by protein phosphorylation. It discusses the use of synthetic peptides in studying the catalytic mechanism and regulation of protein kinases. It also includes the chemical synthesis of phosphorylated peptides and preparation of specific antisera. This incredible work has lead to the development of a new generation of peptide inhibitors with potencies of greater magnitude than those previously known. Everyone involved with biochemistry and molecular biology will find this one-of-a-kind resource fascinating and filled with useful information
