功能 |
Signal transducer and transcription activator that mediates cellular responses to interferons (IFNs), cytokine KITLG/SCF and other cytokines and other growth factors. Following type I IFN (IFN-alpha and IFN-beta) binding to cell surface receptors, signaling via protein kinases leads to activation of Jak kinases (TYK2 and JAK1) and to tyrosine phosphorylation of STAT1 and STAT2. The phosphorylated STATs dimerize and associate with ISGF3G/IRF-9 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 IFN- stimulated genes (ISG), which drive the cell in an antiviral state. In response to type II IFN (IFN-gamma), STAT1 is tyrosine- and serine-phosphorylated. It then forms a homodimer termed IFN- gamma-activated factor (GAF), migrates into the nucleus and binds to the IFN gamma activated sequence (GAS) to drive the expression of the target genes, inducing a cellular antiviral state. Becomes activated in response to KITLG/SCF and KIT signaling. May mediate cellular responses to activated FGFR1, FGFR2, FGFR3 and FGFR4.

总结 |
Stat-1 is a latent transcription factor that functions both as a signal transducer in the cytoplasm and an activator of transcription in the nucleus. Stat-1 is one of seven members of the Signal transducer and activators of transcription (Stats) family (1). Stat-1 is activated by a different number of ligands; IFNα, IFNγ, EGF, PDGF and IL6 (2-3). Upon tyrosine phosphorylation, Stat-1 dimerize with Stat-2 and associates with ISGF3/IR9 to form the ISGF3 complex (4). This activation subsequently allows the complex to translocate to the nucleus & bind specific enhancer elements. Additional complexes can form upon IFN stimulation (1).
