STAT proteins have SH2 domains, and once phosphorylated by JAK kinases, STATs dimerize in a head-to-tail fashion, through their SH2 domains. STAT1 is a critical mediator of IFN signaling, STAT4 is specific to IL-12, STAT6 is activated primarily by IL-4 and IL-13, while STAT5 A and B appear to be most important to the function of growth hormone and prolactin. STAT3 is involved in multiple signaling pathways, and mice deficient in it are not viable. In addition to tyrosine phosphorylation, many STAT proteins are targets of Ser/Thr kinases, and those phosphorylation events potentiate STAT-induced transcription. The phosphorylation state of STATs can be monitored by phosphorylation state-specific antibodies. View All» Species Reactivity:

View All» Key Applications: Western Blotting View All» Entrez Gene Summary: The protein encoded by this gene is a member of the STAT protein family. 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 can be activated by various ligands including interferon-alpha, interferon-gamma, EGF, PDGF and IL6. This protein mediates the expression of a variety of genes, which is thought to be important for cell viability in response to different cell stimuli and pathogens. Two alternatively spliced transcript variants encoding distinct isoforms have been described. [provided by RefSeq] View All» UniProt Summary: Function: Signal transducer and activator of transcription that mediates signaling by interferons (IFNs). Following type I IFN (IFN-alpha and IFN-beta) binding to cell surface receptors, Jak kinases (TYK2 and JAK1) are activated, leading to tyrosine phosphorylation of STAT1 and STAT2. The phosphorylated STATs dimerize, associate with ISGF3G/IRF-9 to form a complex termed ISGF3 transcription factor, that enters the nucleus. ISGF3 binds to the IFN stimulated response element (ISRE) to activate the transcription of interferon stimulated genes, which drive the cell in an antiviral state. In response to type II IFN (IFN-gamma), STAT1 is tyrosine- and serine-phosphorylated. It then forms a homodimer termed IFN-gamma-activated factor (GAF), migrates into the nucleus and binds to the IFN gamma activated sequence (GAS) to drive the expression of the target genes, inducing a cellular antiviral state.Subunit structure: Isoform alpha homodimerizes upon IFN-gamma induced phosphorylation. Heterodimer with STAT2 upon IFN-alpha/beta induced phosphorylation. Interacts with NMI. Interacts with Sendai virus C', C, Y1 and Y2 proteins, Nipah virus P, V and W proteins, and rabies virus phosphoprotein preventing activation of ISRE and GAS promoter By similarity. Interaction with HCV core protein results in STAT1 degradation.Subcellular location: Cytoplasm. Nucleus. Note= Translocated into the nucleus upon activation by IFN-alpha/beta.Post-translational modification: Phosphorylated on tyrosine residues in response to IFN-alpha, IFN-gamma, PDGF and EGF. Serine phosphorylation is also required for maximal transcriptional activity in IFN-gamma transduction (lacking in beta form). Ref.6 Ref.7 Ref.11 Ref.12Involvement in disease: Defects in STAT1 are the cause of STAT1 deficiency [MIM:600555]. Patients generally suffer from mycobacterial or viral diseases. In the case of complete deficiency, patients can die of viral disease. Ref.15Defects in STAT1 are a cause of mendelian susceptibility to mycobacterial disease (MSMD) [MIM:209950]; also known as familial disseminated atypical mycobacterial infection. This rare condition confers predisposition to illness caused by moderately virulent mycobacterial species, such as Bacillus Calmette-Guerin (BCG) vaccine and environmental non-tuberculous mycobacteria, and by the more virulent Mycobacterium tuberculosis. Other microorganisms rarely cause severe clinical disease in individuals with susceptibility to mycobacterial infections, with the exception of Salmonella which infects less than 50% of these individuals. The pathogenic mechanism underlying MSMD is the impairment of interferon-gamma mediated immunity whose severity determines the clinical outcome. Some patients die of overwhelming mycobacterial disease with lepromatous-like lesions in early childhood, whereas others develop, later in life, disseminated but curable infections with tuberculoid granulomas. MSMD is a genetically heterogeneous disease with autosomal recessive, autosomal dominant or X-linked inheritance.
