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 (PubMed:9020188, PubMed:23391734). 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:26122121).3 Publications

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 (PubMed:12509459). Can form a homodimer upon IFN-alpha induced phosphorylation (PubMed:9020188).

Interacts with IFNAR1; the interaction requires the phosphorylation of IFNAR1 at 'Tyr-466' (PubMed:9121453).

Interacts with IFNAR2 (PubMed:9121453).

Interacts with ARL2BP (By similarity).

Interacts with E3 ubiquitin ligase DCST1; the interaction results in STAT2 ubiquitin-mediated proteasomal degradation (PubMed:27782195).

<p>The checksum is a form of redundancy check that is calculated from the sequence. It is useful for tracking sequence updates.</p> <p>It should be noted that while, in theory, two different sequences could have the same checksum value, the likelihood that this would happen is extremely low.</p> <p>However UniProtKB may contain entries with identical sequences in case of multiple genes (paralogs).</p> <p>The checksum is computed as the sequence 64-bit Cyclic Redundancy Check value (CRC64) using the generator polynomial: x<sup>64</sup> + x<sup>4</sup> + x<sup>3</sup> + x + 1. The algorithm is described in the ISO 3309 standard. </p> <p class="publication">Press W.H., Flannery B.P., Teukolsky S.A. and Vetterling W.T.<br /> <strong>Cyclic redundancy and other checksums</strong><br /> <a href="http://www.nrbook.com/b/bookcpdf.php">Numerical recipes in C 2nd ed., pp896-902, Cambridge University Press (1993)</a>)</p> Checksum:iE4C74674CB7A3215
