Abstract
The phosphorylation of tyrosyl residues in proteins is an essential aspect of many signal transduction events, including the control of both normal and neoplastic cell growth and proliferation. Since the earliest observations of tyrosine phosphorylation, it has been appreciated that this is a reversible process in which the net level of phosphate in a target substrate reflects the balance between the competing action of kinases and phosphatases. Thus, in cells transformed by temperature-sensitive mutants of Rous sarcoma virus, an elevation in the levels of phosphotyrosine is observed at the permissive temperature, at which the kinase is active; however, if the cells are shifted to the nonpermissive temperature, at which the kinase is inactivated, a rapid dephosphorylation of tyrosyl residues ensues due to the action of protein tyrosine phosphatases (PTPases) (Sefton et al. 1980). The last 10 years has witnessed great progress in the characterization of the protein tyrosine kinases, whereas...
