Total cell lysates (15 µg protein) from THP-1 (lane 1) and HeLa (lane 2) cells were resolved by electrophoresis (4-20% Tris-Glycine gel), transferred to nitrocellulose, and probed with 0.5 µg/mL Purified anti-IRF 8 Antibody (1:1000 dilution), clone 7G11A45 (upper). Proteins were visualized by chemiluminescence detection using a 1:3000 diluted goat anti-mouse-IgG secondary antibody conjugated to HRP for anti-IRF 8 Antibody, or 1:5000 diluted Direct-Blot HRP anti-β-Actin Antibody, clone 2F1-1 (lower).

    Immunoprecipitation of IRF8 from THP-1 cell extracts. Lane 1 is 5% input. Immunoprecipitation was performed using protein G resins only (lane 2), mouse IgG isotype control (lane 3), and anti-IRF8 antibody (clone 7G11A45, lane 4). Western blot was performed using anti-IRF8 antibody (clone 7G11A45).

Description

IRF8 is a member of the IRF family of transcription factors, playing important roles in IFN signaling pathways and innate immune responses. It regulates hematopoietic cell growth and differentiation of macrophage and dendritic cells. Homozygous IRF8-deficient (IRF8-/-) mice have impaired production of interferon and IL-12, exhibit increased susceptibility to viral pathogens, and have marked expansion of granulocytes that results in a phenotype similar to chronic myelogenous leukemia (CML). IRF8 is also expressed in B lymphocytes, involved in differentiation and commitment of B cell lineage. The DNA-binding activity of IRF8 is significantly increased when interacting with other transcription factors, such as the other members of the IRF family and the ETS family transcription factors. Therefore, the transcriptional activity of IRF8 is dependent on the transcription factors with which it associates.
