This group has been mainly concerned with the regulation of cellular processes by protein phosphorylation, particularly tyrosine phosphorylation. Tyrosine phosphorylation has been implicated in cell growth, proliferation, differentiation and transformation initiated by tyrosine kinases of cellular or viral origin, or linked to hormones and growth factor receptors. Of major interest has been the structure and function of protein tyrosine phosphatases (PTPs) required to catalyze the reverse reaction. Several members of this diverse family of enzymes have been isolated in homogeneous form from various tissues, cloned from various libraries and expressed in different cell types. They represent both transmembrane receptor forms and intracellular enzymes; they are homologous in terms of their catalytic domains but vary greatly in the structure and function of their non-catalytic segments. Special attention is being paid to a family of intracellular PTPs having two SH2 (src-homology 2 domains). Efforts are being made to determine their involvement in signal transduction, sytoskeletal reorganization and cell cycle regulation. Depending on the form of enzyme involved, PTP can act synergistically or antagonistically with the tyrosine kinases in either promoting or preventing neoplastic transformation.
