RNAi of cul-1 decreases lifespan of daf-2 mutant, but not of wild-type or glp-1 mutant. The CUL-1 complex functions in postmitotic, adult somatic tissues of insulin/insulin-like growth factor-1-signaling mutants to enhance longevity. It may act, at least in part, by promoting the transcriptional activity of DAF-16/FOXO [17392428].
