Deficiency of S6 kinase (S6K) extends the lifespan of multiple species, but the underlying mechanisms are unclear. To discover potential effectors of S6K-mediated longevity, we performed a proteomics analysis of long-lived rsks-1/S6K C. elegans mutants compared to wild-type animals. We identified the arginine kinase ARGK-1 as the most significantly enriched protein in rsks-1/S6K mutants. ARGK-1 is...
