IFI44L antibody detects Interferon-induced protein 44-like, an interferon-stimulated gene product that mediates antiviral defense and immune regulation. IFI44L is strongly induced by type I interferons and viral infection and contributes to suppression of viral replication and modulation of innate immune signaling. The IFI44L antibody is widely used in immunology and virology research to study interferon responses and antiviral mechanisms.
IFI44L is encoded by the IFI44L gene on human chromosome 1p31.1. The protein is approximately 444 amino acids in length and localizes primarily in the cytoplasm, with some nuclear presence following interferon stimulation. Although its exact biochemical function remains under investigation, IFI44L is known to interact with cytoskeletal and RNA-binding proteins, influencing viral RNA recognition and replication.
The IFI44L antibody detects a 49 kilodalton protein by western blot and shows diffuse cytoplasmic staining under immunofluorescence microscopy. IFI44L expression is tightly correlated with type I interferon activity, serving as a biomarker for systemic lupus erythematosus and other interferonopathies. It enhances the antiviral state by restricting replication of RNA viruses such as influenza, hepatitis C, and coronaviruses through modulation of double-stranded RNA signaling and translation inhibition.
In addition to antiviral roles, IFI44L modulates immune cell differentiation and inflammation. Elevated IFI44L levels contribute to interferon signature profiles observed in autoimmune diseases, whereas reduced expression can impair viral clearance. Epigenetic regulation of the IFI44L promoter influences susceptibility to immune dysregulation and chronic infection.
Because IFI44L serves as a downstream effector of interferon signaling, it provides a useful marker for evaluating innate immune activation and viral suppression. NSJ Bioreagents provides a validated IFI44L antibody optimized for its applications, supporting research into antiviral defense, immune regulation, and interferon-stimulated gene expression.
Optimal dilution of the IFI44L antibody should be determined by the researcher.
E.coli-derived human IFI44L recombinant protein (Position: R16-I452) was used as the immunogen for the IFI44L antibody.
After reconstitution, the IFI44L antibody can be stored for up to one month at 4oC. For long-term, aliquot and store at -20oC. Avoid repeated freezing and thawing.
