WebNov 11, 2016 · We have identified a serine phosphorylation site (S734) on STAT2 that resides in the TAD, but that is away from the crucial region previously mapped for transactivation. This new site appears to specifically regulate the antiviral activity of type I IFNs, without disturbing the anti-proliferative activity. We consistently show that S734 … WebSep 12, 1997 · Phosphopeptides containing the Stat1 or Stat2 tyrosine phosphorylation sites can prevent Stat1 dimerization ( 20 ). Dimers or heterodimers, but not monomers, are competent to bind DNA. The known DNA binding heterodimers are Stat1:2 (strong binding requires the joint presence of another protein, p48) and Stat1:3 ( 2 ).

WebInterferon-α (IFNα) can activate several members of the signal transducers and activator of transcription (STAT) transcription factor family, a process that requires the tyrosine kinases Jak1 and Tyk2. Here we provide evidence that IFNα-mediated activation of various STAT proteins is regulated by distinct mechanisms. Piceatannol, previously reported as a … WebThere are seven STAT proteins: STAT1, STAT2, STAT3, STAT4, STAT5A, STAT5B and STAT6. [1] STAT proteins contain many different domains, each with a different function, of which the most conserved region is the SH2 domain. [2] The SH2 domain is formed of 2 α-helices and a β-sheet and is formed approximately from residues 575–680.
