To assess the role and specificity of Jaks in Stat activation, we have utilized baculovirus expression systems to produce Stat1 and the Jaks. Co-expression of Stat1 with Tyk2, Jak1, or Jak2 resulted in the specific tyrosine phosphorylation of Stat1 at Tyr701, the residue phosphorylated in mammalian cells stimulated with interferon gamma. Alternatively, Stat1, purified to apparent homogeneity from insect cell extracts, was phosphorylated at Tyr701 in Jak immune complex kinase reactions. Phosphorylation of purified Stat1 was necessary and sufficient for the acquisition of DNA binding activity. The specificity in both systems was indicated by the inability of a Jak2 catalytically inactive mutant (Jak2-Glu882) or the Tec protein-tyrosine kinase to phosphorylate Stat1. However, immune complex-purified epidermal growth factor receptor was capable of phosphorylating purified Stat1 at Tyr701 and activating its DNA binding activity in in vitro reactions."xsd:string |
