Knockout mice with a targeted disruption of Stat2 have higher susceptibility to viral infection and altered responses to type I interferons (3). Stat2 is rapidly activated by phosphorylation at Tyr690 in response to stimulation by IFN-alpha\/beta via associations with receptor-bound Jak kinases (4). Unlike other Stat proteins, Stat2 does not form homodimers. Instead, activated Stat2 forms a heterodimer with Stat1 and translocates to the nucleus. There, it associates with the DNA-binding protein p48 and forms the transcriptional activator complex, interferon-stimulated gene factor 3 (ISGF3), promoting transcription from the ISRE (5).\n\u003cb\u003eAlternate Names\u003c\/b\u003e\nIMD44; interferon alpha induced transcriptional activator; ISGF-3; MGC59816; p113; PTORCH3; Signal transducer and activator of transcription 2; signal transducer and activator of transcription 2, 113kDa; STAT113; STAT2\n\n\u003cb\u003eSpecification\u003c\/b\u003e\n\nREACTIVITY: H R\nSENSITIVITY: Endogenous\nSource\/Isotype: Rabbit IgG","brand":"CST","offers":[{"title":"Default Title","offer_id":46800513007785,"sku":"68826S","price":0.99,"currency_code":"USD","in_stock":true}],"url":"https:\/\/iright.com\/products\/cst-68826s","provider":"Iright","version":"1.0","type":"link"}
