http://purl.uniprot.org/citations/18981155 | http://www.w3.org/2000/01/rdf-schema#comment | "Caspase-1 is an inflammatory caspase that controls the activation and secretion of the inflammatory cytokines, IL-1beta and IL-18. We observed that cellular levels of retinoic acid-inducible gene-I (RIG-I) were enhanced when the pan-caspase inhibitor Z-VAD-fmk or caspase-1-specific inhibitor Z-WEHD-fmk blocked caspase activity. Overexpression of caspase-1 reduced cellular levels of RIG-I and inhibited RIG-I-mediated signaling activity. Enzymatic activity of caspase-1 was necessary to control RIG-I, although it was not a substrate of proteolytic cleavage by caspase-1. Caspase-1 physically interacted with full length RIG-I, but not with mutant forms lacking either the amino- or carboxyl-terminal domains. RIG-I was present in the supernatant of cells transfected with active caspase-1 but not with caspase-4. Stimulating cells with LPS and ATP also induced secretion of endogenous RIG-I in macrophages. Our data suggest a novel mechanism that negatively regulates RIG-I-mediated signaling activity via caspase-1-dependent secretion of RIG-I protein."xsd:string |
