Janus family tyrosine kinases (Jaks) and signal transducers and activators of transcription (STATs) are involved in mediating gene expression in response to cytokines and interferons. Jaks associate with cytokine receptors; upon ligand binding, Jaks phosphorylate the receptor. The phosphorylated receptors are bound by SH2-containing proteins, one class of which is the STATs. Activated STATs, then, translocate to the nucleus to mediate gene transcription (1,2). Stat4 is a signal transducer and activator of transcription. It is specifically involved in IL-12 signaling. Human Stat4 is phosphorylated on serine 721, tyrosine 355, and tyrosine 693. Phosphorylation at tyrosine leads to induces interaction with Stat3, while Stat4 phosphorylation at serine is linked to the requirement for maximal transcriptional activity (3).
