Using these T cells as a model of IL-12 signal transduction , we confirmed that these events involve members of the Janus kinase family of nonreceptor tyrosine kinases JAK2 , TYK2 , and signal transducer and activator of transcription 4 .
 protein: TYK2; protein: nonreceptor tyrosine kinases; protein: Janus kinase family; protein: signal transducer and activator of transcription 4; protein: JAK2; cell type: T cells; protein: IL-12
