Anti-STAT2 Antibody Picoband®

Signal transducer and activator of transcription 2 (STAT2) is a protein that in humans is encoded by the STAT2 gene. The protein encoded by this gene is a member of the STAT protein family. The International Radiation Hybrid Mapping Consortium mapped the STAT2 gene to chromosome 12. STAT2 is a transcription factor critical to the signal transduction pathway of type I interferons. ISGF3 (STAT2) assembly involves p48 functioning as an adaptor protein to recruit Stat1 and Stat2 to an IFN-alpha-stimulated response element, Stat2 contributes a potent transactivation domain but is unable to ly contact DNA, while Stat1 stabilizes the heteromeric complex by contacting DNA ly.

A synthetic peptide corresponding to a sequence at the N-terminus of human STAT2, which shares 73.5% and 76.5% amino acid (aa) sequence identity with mouse and rat STAT2, respectively.

Signal transducer and activator of transcription that mediates signaling by type I IFNs (IFN-alpha and IFN-beta) . Following type I IFN binding to cell surface receptors, Jak kinases (TYK2 and JAK1) are activated, leading to tyrosine phosphorylation of STAT1 and STAT2. The phosphorylated STATs dimerize, associate with IRF9/ISGF3G to form a complex termed ISGF3 transcription factor, that enters the nucleus. ISGF3 binds to the IFN stimulated response element (ISRE) to activate the transcription of interferon stimulated genes, which drive the cell in an antiviral state (PubMed:9020188, PubMed:23391734) . Acts as a regulator of mitochondrial fission by modulating the phosphorylation of DNM1L at 'Ser-616' and 'Ser-637' which activate and inactivate the GTPase activity of DNM1L respectively (PubMed:26122121) .
