Interferon regulatory factors (IRFs) comprise a family of transcription factors that function within the Jak/Stat pathway to regulate interferon (IFN) and IFN-inducible gene expression in response to viral infection (1). IRFs play an important role in pathogen defense, autoimmunity, lymphocyte development, cell growth, and susceptibility to transformation. The IRF family includes nine members: IRF-1, IRF-2, ISGF3γ/p48, IRF-3, IRF-4 (Pip/LSIRF/ICSAT), IRF-5, IRF-6, IRF-7, and IRF-8/ICSBP. All IRF proteins share homology in their amino-terminal DNA-binding domains. IRF family members regulate transcription through interactions with proteins that share similar DNA-binding motifs, such as IFN-stimulated response elements (ISRE), IFN consensus sequences (ICS), and IFN regulatory elements (IRF-E) (2).

干扰素调控因子(IRFs) 包含一个家族的转录调控因子,这个家族主要是在 Jak/Stat信号通路中起作用,在受到病毒的感染后能够调控干扰素(IFN)和干扰素诱导的基因表达(1)。IRFs在抵抗病原菌、自体免疫、淋巴细胞发育、细胞生长和易感性的转变等过程中发挥了重要的作用。IRF家族包含9个成员: IRF-1、IRF-2、ISGF3γ/p48、IRF-3、 IRF-4 (Pip/LSIRF/ICSAT)、 IRF-5、 IRF-6、 IRF-7和IRF-8/ICSBP。所有的IRF蛋白在N-末端的DNA-结合区域都具有同源性。IRF家族成员通过与具有相似DNA-结合区域(例如IFN刺激的应答原件(ISRE)、IFN consensus序列 (ICS) 和IFN 调控元件(IRF-E)) 的蛋白相互作用而调控转录(2)。
