Recombinant human IL28RA protein is a key component in studying the interferon (IFN)-λ signaling pathway. IL28RA, also known as interferon lambda receptor 1. is a transmembrane protein encoded by the IL28RA gene. It forms part of the heterodimeric receptor complex for type III interferons (IFN-λ1/IL-29. IFN-λ2/IL-28A, and IFN-λ3/IL-28B), pairing with IL10RB (IL-10 receptor β subunit). This receptor-ligand interaction triggers JAK-STAT signaling cascades, inducing antiviral responses and modulating immune activities in epithelial and immune cells.
Recombinant IL28RA is typically produced in expression systems like mammalian cells or E. coli, enabling controlled studies of its structure, ligand-binding properties, and downstream signaling mechanisms. Its applications span basic research on viral pathogenesis (e.g., hepatitis B/C, influenza), autoimmune disorders, and cancer immunotherapy development. Unlike type I IFN receptors, IL28RA exhibits tissue-specific expression patterns, making it crucial for understanding localized immune responses at mucosal barriers. Pharmaceutical efforts focus on leveraging IFN-λ's targeted antiviral effects with potentially reduced systemic side effects compared to type I IFNs. Current studies also explore IL28RA polymorphisms linked to treatment outcomes in chronic infections and inflammatory diseases.
