| 来源宿主 | Rabbit |
| 应用 | W |
| 目标/特异性 | Phospho-Stat2 Antibody detects endogenous levels of human Stat2 only when phosphorylated at Tyr690. The antibody does not significantly cross-react with corresponding phospho-tyrosine sites on other Stat proteins. |

| 背景 | Stat2 (113-kDa), originally purified from the nuclei of alpha-interferon-treated cells, is critical to the transcriptional responses induced by type I interferons, IFN-alpha/beta (1,2). 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). |
