ERI-1 is a 3'→5' RNA exonuclease that degrades small RNAs, including siRNAs and other non-coding RNAs involved in RNA interference (RNAi). By degrading these regulatory small RNAs, ERI-1 acts as a negative regulator of the RNAi pathway in C. elegans. Loss-of-function mutations in eri-1 enhance RNAi efficiency, which in turn can potentiate silencing of genes that promote aging (e.g., components of insulin/IGF-1 signaling). Since ERI-1's normal function suppresses RNAi-mediated gene silencing, its activity opposes the pro-longevity effects of endogenous small RNA pathways. Additionally, endogenous small RNAs regulated by ERI-1 may target transcripts involved in stress resistance and proteostasis, meaning ERI-1-mediated degradation of these RNAs would reduce stress resilience and shorten lifespan.

GenAge curators classify each gene's normal function as promoting (Pro-Longevity) or opposing (Anti-Longevity) longevity, based on synthesis across studies. Loss-of-function effects can vary from this depending on the manipulation.

Notes

The model predicted anti_longevity but the ground truth is pro_longevity. The model's mechanistic reasoning about ERI-1 as a negative regulator of RNAi is broadly correct (ERI-1 degrades siRNAs and suppresses RNAi), but the model drew the wrong conclusion about the longevity effect. The model reasoned that because ERI-1 suppresses RNAi, it would suppress pro-longevity RNAi effects, making it anti-longevity. However, the actual finding is that ERI-1 is pro-longevity. The model's logic about the downstream consequences was flawed - it failed to account for the possibility that ERI-1's regulation of endogenous small RNAs could itself promote longevity through mechanisms beyond simply suppressing RNAi. The model was fairly confident (0.72) in its wrong answer.
