    STAT4 Summary & Protein Information

    STAT4 Background

    Gene Summary: The protein encoded by STAT4 gene 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 gene may be associated with systemic lupus erythematosus and rheumatoid arthritis. Alternate splicing results in multiple transcript variants that encode the same protein.

    General information above from NCBI
    Subunit structure: Forms a homodimer or a heterodimer with a related family member. Interacts with ARL2BP (By similarity). The SH2 domain interacts, in vitro, with IL12RB2 via a short cytoplasmic domain.
    Subcellular location: Cytoplasm. Nucleus. Note=Translocated into the nucleus in response to phosphorylation.
    Post-translational: Tyrosine phosphorylated. Serine phosphorylation is also required for maximal transcriptional activity (By similarity).
    Involvement in disease: Systemic lupus erythematosus 11 (SLEB11) [MIM:612253]: A chronic, relapsing, inflammatory, and often febrile multisystemic disorder of connective tissue, characterized principally by involvement of the skin, joints, kidneys and serosal membranes. It is of unknown etiology, but is thought to represent a failure of the regulatory mechanisms of the autoimmune system. The disease is marked by a wide range of system dysfunctions, an elevated erythrocyte sedimentation rate, and the formation of LE cells in the blood or bone marrow. Note=Disease susceptibility is associated with variations affecting the gene represented in this entry.
    Rheumatoid arthritis (RA) [MIM:180300]: An inflammatory disease with autoimmune features and a complex genetic component. It primarily affects the joints and is characterized by inflammatory changes in the synovial membranes and articular structures, widespread fibrinoid degeneration of the collagen fibers in mesenchymal tissues, and by atrophy and rarefaction of bony structures. Note=Disease susceptibility is associated with variations affecting the gene represented in this entry.
    Sequence similarity: Belongs to the transcription factor STAT family.
    Contains 1 SH2 domain.
