General description

Mouse Interferon regulatory factor 7 or IRF-7 (UniProt P70434) is encoded by the murine irf7 gene (Entrez Gene ID 54123). IFN-γ-induced gene activations are mediated by both signal transducers and activators of transcription (STATs) and interferon regulatory factors (IRFs). STAT1 dimer, for example, stimulates immediate transcription by binding IFN-γ-activated site (GAS) sequence in the promoter region of target genes. While a delayed, secondary transcription activation is observed among IFN-γ target genes containing an IFN regulatory factors (IRF) binding site within the interferon-stimulated response element (ISRE) sequence. Irf7 transcription is shown to be activated by STAT1 and IRF9 in response to type II interferon (IFN) IFN-γ stimulation in MEF cultures. The expressed IRF7 protein then further cooperates with STAT1 and IRF1 to stimulate the expression of a subset of IFN-γ-induced STAT1 target genes. Cat. No. ABF130, Anti-IRF7 is a rabbit polyclonal antiserum raised against recombinant GST fusion protein encompassing murine IRF7 C-terminal half sequence. This antiserum specifically detects INF-gamma-induced IRF7 expression and chromatin association in Wt, but not Irf7-/- MEF by Western blotting and ChIP application, respectively. Murine IRF7 has a calculated M.W. of 51.2 kDa, but migrates with an apparent M.W. of ~60 kDa by SDS-PAGE.

Signal transducers and activators of transcription (STATs) and interferon regulatory factors (IRFs) share common target genes. Here we show that the Irf7 gene is regulated by transcription factors STAT1 and IRF9 in response to the type II interferon (IFN) IFN-γ.
