The protein encoded by STAT4（signal transducer and activator of transcription 4） is a member of the STAT family of transcription factors. In response to cytokines and growth factors, STAT family members are phosphorylated by the receptor associated kinases, and then form homo- or heterodimers that translocate to the cell nucleus where they act as transcription activators. This protein is essential for mediating responses to IL12 in lymphocytes, and regulating the differentiation of T helper cells. Mutations in STAT4 may be associated with systemic lupus erythematosus and rheumatoid arthritis. Alternate splicing results in multiple transcript variants that encode the same protein.蛋白別名為：STAT4; Signal transducer and activator of transcription 4;基因ID為：6775；蛋白質ID:Q14765
