| Description | RNAi of atp-3 by bacterial feeding increases life-span by 46% (Dillin et al., 2002). RNAi of atp-3 during larval stages is necessary and sufficient for increased life-span. RNAi of atp-3 only during adulthood fails to extend life-span. |

| Gene Function | Subunit of mitochondrial ATP synthase. |

| Other Phenotypes | RNAi of atp-3 results in reduced pharyngeal pumping, defecation, and motility. ATP levels are reduced by 60- 80% in atp-3 animals and body size is reduced (Dillan et al., 2002).
Mutation of daf-16 fails to prevent life-span extension by RNAi of atp-3 and mutation of daf-2 further extends the life span of atp-3 RNAi animals. |
