25794939 This review briefly summarizes the RLR system, and focuses on the relationship between LGP2 and MDA5, describing in detail how these two proteins work together to detect foreign RNA and generate a fully functional antiviral response.
25288302 LGP2 did not reveal significant single-SNP associations with multiple sclerosis risk.
25127512 LGP2 increases the initial rate of MDA5-RNA interaction and regulates MDA5 filament assembly.
24829334 Experiments with paramyxovirus V protein-insensitive proteins revealed that the primary outcome of LGP2 interference is suppression of its ability to synergize with MDA5.
24550253 L region antisense RNA of EMCV is a key determinant of innate immunity to the virus and represents an RNA that activates LGP2 associated MDA5 in virally-infected cells.
23671710 Data show that LGP2 is able to synergize with melanoma differentiation associated gene-5 (mda-5) to render cells to induction by poly(I:C), but did not enhance retinoic acid-inducible gene-I (RIG-I) to induce type I interferon in response to poly(I:C).
23184951 results demonstrate previously unrecognized properties of LGP2 ATP hydrolysis and RNA interaction and provide a mechanistic basis for a positive regulatory role for LGP2 in antiviral signaling
22837208 LGP2, a host protein induced during influenza A virus infection, downregulates the host antiviral IFN response
22301134 Paramyxovirus 5 V proteins interact with the RNA Helicase LGP2 to inhibit RIG-I-dependent interferon beta induction.
22185736 the present study shows the presence of RIG-1,MDA-5, and LGP-2 in the human upper airways, most prominently inthe epithelium.
21525357 LGP2 functions as an inhibitor of the innate immune response triggered by Rabeis virus infection
21285412 Data sugget that DeltaPsi(m) and MAVS are coupled at the same stage in the RLR antiviral signaling pathway.
20331378 Observational study of gene-disease association. (HuGE Navigator)
19403670 The V protein interaction was found to disrupt ATP hydrolysis mediated by both MDA5 and LGP2.
19278996 The RIG-I-like receptor LGP2 recognizes the termini of double-stranded RNA.
18976975 Knockdown of DEXH (Asp-Glu-X-His) box polypeptide 58 (DHX58) by siRNA inhibits HIV-1 replication in HeLa P4/R5 cells
18411269 LGP2 can be coexpressed with RIG-I to inhibit activation of the NF-kappaB reporter expression and that LGP2 protein produced in insect cells can bind both single- and double-stranded RNA (dsRNA), with higher affinity and cooperativity for dsRNA.
17020950 LGP2 competes with the kinase IKKi for a common interaction site on IPS-1, as an element of negative-feedback regulation of intracellular antiviral signaling.
16116171 Shared and unique functions of the DExD/H-box helicases RIG-I, MDA5, and LGP2 in antiviral innate immunity.
11735219 Cloning and expression of the mouse Lpg2 mRNA, and comparison of the ORF to that of human LPG2 mRNA.
