Laboratory of Genetics and Physiology 1 (LGP1), also known as DHX58. is a cytosolic RNA helicase belonging to the RIG-I-like receptor (RLR) family, which plays a critical role in innate antiviral immunity. Unlike other RLRs (RIG-I and MDA5), LGP1 lacks caspase activation and recruitment domains (CARDs) but retains conserved helicase and C-terminal regulatory domains. It functions as a regulatory sensor for viral RNA, particularly long double-stranded RNA (dsRNA), and modulates immune signaling pathways. LGP1 enhances or suppresses antiviral responses depending on viral context, often by interacting with RIG-I or MDA5 to fine-tune their activities. Recombinant human LGP1 protein is typically produced in bacterial (e.g., E. coli) or mammalian expression systems, enabling studies on its RNA-binding specificity, ATPase activity, and interaction partners. Its applications include elucidating mechanisms of viral RNA recognition, immune evasion strategies of pathogens, and developing broad-spectrum antiviral therapies. Research on recombinant LGP1 also contributes to understanding autoimmune disorders and cancer immunotherapy, where dysregulated RLR signaling is implicated. As a tool, it aids in dissecting the nuanced roles of helicases in antiviral defense and their potential as therapeutic targets.
