PTMs - P52630 As Substrate
Signal transducer and activator of transcription that mediates signaling by type I IFNs (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. 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.
Tyrosine phosphorylated in response to IFN-alpha. Phosphorylation at Ser-287 negatively regulates the transcriptional response.
'Lys-48'-linked ubiquitination by DCST1 leads to STAT2 proteasomal degradation.
Note: Translocated into the nucleus upon activation by IFN-alpha/beta.
Heterodimer with STAT1 upon IFN-alpha/beta induced phosphorylation (By similarity). The heterodimer STAT1:STAT2 forms the interferon-stimulated gene factor 3 complex (ISGF3) with IRF9; interacts with IRF9 in the cytoplasm (By similarity). Interacts with CRSP2 and CRSP6. Can form a homodimer upon IFN-alpha induced phosphorylation. Interacts with IFNAR1; the interaction requires the phosphorylation of IFNAR1 at 'Tyr-466'. Interacts with IFNAR2. Interacts with ARL2BP (By similarity). Interacts with E3 ubiquitin ligase DCST1; the interaction results in STAT2 ubiquitin-mediated proteasomal degradation.
(Microbial infection) Interacts with vaccinia virus protein C6.
(Microbial infection) Interacts with Simian virus 5 protein V.
(Microbial infection) Interacts with Rabies virus phosphoprotein.
(Microbial infection) Interacts with Human cytomegalovirus/HHV-5 protein UL123; this interaction promotes viral growth.
(Microbial infection) Interacts with Dengue virus NS5; this interaction inhibits the phosphorylation of STAT2, and, when all viral proteins are present (polyprotein), targets STAT2 for degradation.
Belongs to the transcription factor STAT family.
