Total lysates (15 µg protein) from HeLa (lane 1), Molt-4 (lane 2) and NIH3T3 (lane 3) were resolved by electrophoresis (4-12% Bis-Tris gel), transferred to nitrocellulose, and probed with 1:500 diluted (1 µg/mL) purified anti-IRF1 antibody (upper). Proteins were visualized using an HRP goat anti-mouse-IgG secondary antibody (Cat. No. 405306) or HRP Donkey anti-rabbit IgG Antibody (Cat. No. 406401) for GAPDH and chemiluminescence detection. GAPDH (poly6314, Cat. No. 631401) antibody was used as a loading control (lower). Lane M: MW ladder.

    HeLa cells were fixed with 2% PFA for ten minutes, permeabilized with 0.5% Triton X-100 for five minutes, and blocked with 5% FBS for 30 minutes. Then the cells were intracellularly stained with 2 µg/mL anti-IRF1 Antibody (clone 13H3A44) followed by Alexa Fluor® 594 (red) conjugated goat anti-mouse IgG in blocking buffer for two hours at room temperature. Actin filaments were labeled with Alexa Fluor® 488 Phalloidin (green). Nuclei were counterstained with DAPI (blue). The image was captured with a 60X objective.

    Immunoprecipitation of IRF1 from Hela cells treated with human IFNg (100 ng/ml, 4 hr). Lane 1 is 5% input. Immunoprecipitation was performed using protein G resins only (lane 2), mouse IgG isotype control (lane 3), and anti-IRF1 antibody (clone 13H3A44, lane 4). Western blot was performed using anti-IRF1 antibody (clone 13H3A44).

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.
