Synonyms:Caterpiller protein 11.3, CLR11.3, DLNB26, NLR family member X1, NLRX1, NOD26, NOD5, NOD9 Background:Participates in antiviral signaling. Acts as a negative regulator of MAVS-mediated antiviral responses, through the inhibition of the virus-induced RLH(RIG-like helicase)-MAVS interaction(PubMed:18200010). Has no inhibitory function on NF-Kappa-B and type 1 interferon signaling pathways, but enhances NF-Kappa-B and JUN N-terminal kinase dependent signaling through the production of reactive oxygen species(PubMed:18219313).
