The JAK family of receptor-associated protein kinases is directly involved in interferon (IFN) response pathways. The JAK family contains at least three members: JAK1, JAK2, and Tyk2. Each protein is approximately 130kDa and contains a C-terminal tyrosine kinase domain, an adjacent kinase or kinase-related domain, and five other domains that are highly conserved among family members. In several human and murine cell lines, JAK1 is rapidly tyrosine phosphorylated in response to IFN-α and IFN-γ. JAK1 is required for the phosphorylation of the transcription factor Stat1 (p91), in response to IFNs-α or IFN-γ. JAK1 is also necessary for the efficient phophorylation of Stat2 (p113) in response to IFN-α and for the phosphorylation of Tyk2 or JAK2 in response to IFNs-α or IFN-γ, respectively.Immunofluorescence, Immunohistochemistry, Immunoprecipitation, Western Blotting
