The putative ATP-dependent RNA helicase LGP2 is encoded by the DHX58 gene in humans. LGP2 is also known as DEXH (Asp-Glu-X-His) box polypeptide 58; probable ATP-dependent RNA helicase DHX58, DHX58, protein D11Lgp2 homolog, RIG-I-like receptor LGP2, RLR, RLR3, D11LGP2, and D11LGP2E. LGP2 was first identified in mammary tissue, but its function was subsequently found to be more relevant in innate antiviral immunity. It is essential for producing effective antiviral responses against many viruses that are recognized by the receptors DDX58/RIG-I and IFIH1/MDA5. This role of LGP2, which can have both positive and negative regulatory effects, is complex and depends on the characteristics of the infecting virus and the target cells. It is suggested that its positive regulatory role may involve unwinding or stripping nucleoproteins of viral RNA, thereby facilitating their recognition by viral receptors. LGP2 binds to ds RNA with high affinity, but it can also bind ss RNA.
This product is an affinity-purified IgG antibody that recognizes human LGP2 protein. The antibody was raised in rabbit using a synthetic peptide. It can be used for Western blot (WB) detection of human LGP2 protein.
