Supplementary information

The Signal Transducer and Activator of Transcription 2 commonly known as STAT2 is a protein with a molecular mass of approximately 97 kDa. It functions mainly as a transcription factor and is an essential mediator of the interferon (IFN) signaling pathway. STAT2 is expressed in various tissues including immune cells where it responds to external stimuli. It works by translocating to the nucleus upon phosphorylation subsequently influencing the expression of genes involved in immune response.
Biological function summary

Members of the STAT protein family including STAT2 play a central role in mediating immune responses. STAT2 often forms a complex with STAT1 and other proteins such as IRF9 to initiate the transcription of interferon-stimulated genes (ISGs). This complex known as the ISGF3 complex facilitates the cellular response to viral infections by promoting the expression of antiviral proteins that help modify the host cellular environment to resist viral replication.

Pathways

The involvement of STAT2 is closely associated with the JAK-STAT signaling pathway and the interferon signaling pathway. In these pathways it interacts with proteins like JAK1 TYK2 and STAT1 playing a part in transmitting signals from the cell surface to the nucleus. Such pathways are fundamental to regulating the body's immune response to pathogens and managing cell growth and apoptosis in various cells.

STAT2 alterations have been linked to autoimmune diseases and viral infections. Disruptions in STAT2 function can impair the body's ability to combat viruses effectively making individuals more susceptible to infections. STAT2 mutations or dysregulations might also connect to disorders like Systemic Lupus Erythematosus where immune system malfunctions occur. The interactions of STAT2 with other proteins like STAT1 and IRF9 in disease contexts underline its importance in maintaining immune system balance.

Target data

Signal transducer and activator of transcription that mediates signaling by type I interferons (IFN-alpha and IFN-beta). Following type I IFN 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 IRF9/ISGF3G 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 (PubMed : 23391734, PubMed : 9020188). In addition, has also a negative feedback regulatory role in the type I interferon signaling by recruiting USP18 to the type I IFN receptor subunit IFNAR2 thereby mitigating the response to type I IFNs (PubMed : 28165510). Acts as a regulator of mitochondrial fission by modulating the phosphorylation of DNM1L at 'Ser-616' and 'Ser-637' which activate and inactivate the GTPase activity of DNM1L respectively (PubMed : 23391734, PubMed : 26122121, PubMed : 9020188).
