| Background Information | Interferon-induced protein with tetratricopeptide repeats 3 (UniProt Q64345; also known as GARG-49, Glucocorticoid-attenuated response gene 49 protein. IFIT-3, IRG2, p49) is encoded by the Ifit3 (also known as Garg49, Ifi49, Isg49) gene (Gene ID 5959) in murine species. IFIT1, IFIT2, and IFIT3 constitute the family of interferon-stimulated genes (ISGs) that are induced in response to virus infection, stimulation by interferons (IFNs), or double-stranded RNA (dsRNA). The proteins encoded by IFIT1 and IFIT2 are called ISG56 (p56) and ISG54 (p54) in both human and murine species, while the protein encoded by IFIT3 is of a different size in murine (ISG49 or p49) than its human counterpart (ISG60 or p60). Studies conducted in murine species reveals that the three members exhibit distinct properties and induction patterns in different cell types. While all three murine proteins are shown to bind the c-subunit of the translation initiation factor eIF3, p49/Ifit3 does not inhibit protein synthesis as p56/Ifit1 and p54/Ifit2. |

| Application Notes | Western Blotting Analysis: A 1:2,500 dilution of this antibody detected IFIT3 in 40 µg of IFN beta treated RAW264.7 cell lysate (Courtesy of Dr. Ganes C. Sen, Cleveland Clinic, OH). Western Blotting Analysis: A representative lot detected Ifit3/ISG49 induction in RAW264.7 and wild-type, but not IRF3 or Stat1 knockout, MEFs upon Sendai virus/SeV infection, dsRNA or INF-beta stimulation in cultures, as well as in liver/lung/spleen/colon tissues from mice after dsRNA or INF-alpha i.v. injection (Fensterl, V., et al. (2008). J Virol. 82(22):11045-11053). Western Blotting Analysis: A representative lot detected differential Ifit3/ISG49 inductions between murine MPC podocytes and primary murine glomerular mesangial cells in response to Sendai virus (SeV), encephalomyocarditis virus (EMCV), and vesicular stomatitis virus (VSV) infection (Fensterl, V., et al. (2008). J Virol. 82(22):11045-11053). Western Blotting Analysis: A representative lot selectively detected exogenously expressed murine Ifit3/ISG49 and human IFIT3/ISG60, but not murine Ifit1/ISG56 or Ifit2/ISG54, in transfected HT1080 cells (Fensterl, V., et al. (2008). J Virol. 82(22):11045-11053). Western Blotting Analysis: A representative lot detected Ifit3/ISG49 induction in IFN-alpha-stimulated primary murine spleen B cells and in IFN-beta-stimulated MEFs (Fensterl, V., et al. (2008).

Immunoprecipitation Analysis: A representative lot selectively immunoprecipitated exogenously expressed murine Ifit3/ISG49, but not Ifit1/ISG56, from transfected MEFs (Fensterl, V., et al. (2008). J Virol. 82(22):11045-11053). Immunohistochemistry Analysis: A representative lot detected differential Ifit3/ISG49 induction among various cell types in formaldehyde-fixed, paraffin-embedded kidney tissue sections from mice after Sendai virus (SeV) or dsRNA i.v. injection (Fensterl, V., et al. (2008). J Virol. 82(22):11045-11053). Flow Cytometry Analysis: A representative lot detected IFN-beta-induced Ifit3/ISG49 immunoreactivity using murine bone marrow-derived dendritic cells, as well as isolated CD3+ (T cells) and B220+ (B cells) peripheral blood cells (Fensterl, V., et al. (2008). J Virol. 82(22):11045-11053). Immunocytochemistry Analysis: A representative lot detected IFN-beta-induced Ifit3/ISG49 expression in MEFs (Fensterl, V., et al. (2008). J Virol. 82(22):11045-11053). Flow Cytometry Analysis: A representative lot (1:500 dilution) detected IFN-beta-induced Ifit3/ISG49 immunoreactivity in primary murine macrophages (Courtesy of Dr. Ganes C. Sen, Cleveland Clinic, OH). |
