function: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).,sequence caution:Translated as Trp.,sequence caution:Translation N-terminally extended.,similarity:Belongs to the NLRP family.,similarity:Contains 1 NACHT domain.,similarity:Contains 4 LRR (leucine-rich) repeats.,subunit:Interacts with MAVS.,tissue specificity:Ubiquitously expressed. Strongest expression in mammary gland, heart and muscle. Detected in HELA, 293T, THP-1, HL60, RAJI, and JURKAT cell lines (at protein level).,
