Stat2 phosphorylation

WebIn this study, we show that SARS-CoV-2 is able to efficiently block STAT1 and STAT2 nuclear translocation in order to impair transcriptional induction of IFN-stimulated genes (ISGs). Our results demonstrate that the viral accessory protein Orf6 exerts this anti-IFN activity. WebThe IL-12 receptor is a heterodimer that consists of IL-12Rβ2 and IL-12Rβ1, which are coupled to the Janus kinases JAK2 and TYK2. After phosphorylation by JAK2 or TYK2, STAT4 or STAT1 dimerizes and is translocated to the nucleus, where dimer binding induces gene transcription.
