|Homo sapiens interferon regulatory factor 3 (IRF3), transcript variant 1|
|MGC94729; interferon regulatory factor 3|
|A family of interferon (IFN) regulatory factors (IRFs) have been shown to play a role in transcription of IFN genes as well as IFN-stimulated genes. The IRF-3 gene encodes a 50-kDa protein that binds specifically to the IFN-stimulated response element (ISRE) but not to the IRF-1 binding site PRD-I. Overexpression of IRF-3 stimulates expression of the IFN-stimulated gene 15 (ISG15) promoter, an ISRE-containing promoter. he high amino acid homology between IRF-3 and ISG factor 3 gamma polypeptide (ISGF3 gamma) and their similar binding properties indicate that, like ISGF3 gamma, IRF-3 may activate transcription by complex formation with other transcriptional factors, possibly members of the Stat family (1). IRF-3 is expressed constitutively in a variety of tissues, and the relative levels of IRF-3 mRNA do not change in virus-infected or IFN-treated cells. (2). In uninfected cells, the IRF-3 component of DRAF1 resides in the cytoplasm. The cytoplasmic localization of IRF-3 is dependent on a nuclear export signal, and IRF-3 is recognized by the chromosome region maintenance 1 (CRM1) (also known as exportin 1) shuttling receptor. Following infection and specific phosphorylation, IRF-3 accumulates in the nucleus where it associates with CBP and p300 (3). |

Immunohistochemistry (Formalin/PFA-fixed paraffin-embedded sections) - IRF3 antibody [EPR2418Y]; TA301179 at 1/100 dilution staining IRF3 in human tonsil by Immunohistochemistry, Paraffin-embedded tissue.
Flow Cytometry - Anti-IRF3 antibody [EPR2418Y]; Overlay histogram showing HeLa cells stained with TA301179 (red line). The cells were fixed with 80% methanol (5 min) and then permeabilized with 0.1% PBS-Tween for 20 min. The cells were then incubated in 1x PBS / 10% normal goat serum / 0.3M glycine to block non-specific protein-protein interactions followed by the antibody for 30 min at 22Â°C. The secondary antibody used was Alexa Fluor? 488 goat anti-rabbit IgG (H&L) at 1/2000 dilution for 30 min at 22Â°C. Isotype control antibody (black line) was rabbit IgG (monoclonal) (1Âµg/1x10^6 cells) used under the same conditions. Unlabelled sample (blue line) was also used as a control. Acquisition of >5,000 events were collected using a 20mW Argon ion laser (488nm) and 525/30 bandpass filter.
