WebSTAT2 contributes its strong transactivation domain to ISGF3 (2), IRF9 contributes the principal DNA binding domain, and STAT1 stabilizes the complex and also provides additional DNA contacts (3). Notably, the STAT1, STAT2, and IRF9genes are all ISGs that are strongly induced by type I IFNs. WebMar 2, 2007 · As critical components of ISGF3, STAT1 and STAT2 are potential targets for IKKϵ. We therefore investigated the status of these two transcription factors in response to IFN in Ikbke–/– mice. Initially, we carried out Western blot experiments with primary lung extracts from mice infected with different viruses. teacher burnout definition https://juancarloscolombo.com

WebJun 1, 2016 · STAT2 is best known to participate, together with STAT1 and IRF9, in the formation of the ISGF3 complex, which binds ISRE elements. In ISGF3, STAT2 contributes a potent TAD but is unable to directly contact DNA, whereas STAT1 stabilizes the complex by providing additional DNA contacts [39].

However, the co-localization of STAT2 and STAT1-NLS was lost upon the alanine mutation of STAT2 hot spot interface residue L82 (Fig. 5C

WebOct 25, 2016 · STAT2 is the quintessential transcription factor for type 1 interferons (IFNs), where it functions as a heterodimer with STAT1. However, the human and murine STAT2-deficient phenotypes suggest important additional and currently unidentified type 1 IFN-independent activities.
