Stat2 phosphorylation

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. WebSTAT2 is an essential transcription factor in type I IFN mediated anti-viral and anti-proliferative signaling. STAT2 function is regulated by tyrosine phosphorylation, which is the trigger for STAT-dimerization, subsequent nuclear translocation, and transcriptional activation of IFN stimulated genes.
