|Application ||WB, IHC|
|Calculated MW||97916 Da|
|Other Names||Signal transducer and activator of transcription 2, p113, STAT2|
|Target/Specificity||A synthetic peptide corresponding to residues near N-terminus of human Stat-2 was used as immunogen. This antibody detects both long and short forms of Stat-2.|
|Format||50 mM Tris-Glycine (pH 7.4), 0.15 M NaCl, 40% Glycerol, 0.01% sodium azide and 0.05% BSA.|
|Storage||Maintain refrigerated at 2-8°C for up to 6 months. For long term storage store at -20°C in small aliquots to prevent freeze-thaw cycles.|
|Precautions||Stat-2 Antibody is for research use only and not for use in diagnostic or therapeutic procedures.|
|Function||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).|
|Cellular Location||Cytoplasm. Nucleus Note=Translocated into the nucleus upon activation by IFN- alpha/beta.|

Stat-2 is a latent transcription factor that functions both as a signal transducer in the cytoplasm and an activator of transcription in the nucleus. Stat-2 is one of seven members of the Signal transducer and activators of transcription (Stats) family. Stat-2 is phosphorylated at Tyr690 by JAKs(1-3). Additionally, upon activation, Stat-2 will form a multiprotein DNA-binding complex with Stat-1 and ISGF3γp48 (4). This activation subsequently allows the complex to translocate to the nucleus & bind specific enhancer elements.
