W17068C_PURE_IRF1_Antibody_112421
Human peripheral blood mononuclear cells were treated with recombinant human IFN- γ overnight. Cells were fixed and permeabilized with True-Nuclear™ Transcription Factor Buffer Set, and stained intracellularly with purified anti-human IRF1 (clone W17068A) (filled histogram) or purified rat IgG2a, κ isotype control (open histogram), followed by anti-rat IgG PE. Data shown are cells from the monocyte population.

Description

IRF1 is the first identified member of the interferon regulatory transcription factor family. Its expression is induced in response to pathogen infection or the stimulation of several cytokines, including type I and II IFN, IL-1, IL-6, and TNF-α. Upon stimulation, IRF1 is transcriptionally activated by STAT1 and NFκB transcription factors via the GAS (interferon-gamma-activated sequence) element in the IRF1 promoter. IRF1 plays important roles in mediating immune response during infection and development of T cells and NK cells. In addition to the immunomodulatory functions, IRF1 has also shown to be involved in the regulation of cell cycle progression, tumor suppression, and apoptosis. IRF1-mediated transcription can be repressed by IRF2 through competing for the same binding region on the promoters.
