Solver output
rpc-1 encodes a subunit of RNA Polymerase III (Pol III), which is responsible for transcribing small non-coding RNAs including tRNAs, 5S rRNA, and other structural RNAs essential for protein synthesis capacity. Pol III activity is regulated by nutrient-sensing pathways (mTORC1/TORC1), and its repression is associated with lifespan extension in multiple organisms including yeast and C. elegans. However, Pol III is also fundamentally required for cellular homeostasis and proteostasis through tRNA production. The net effect on longevity is ambiguous from molecular function annotations alone: while Pol III overactivity is anti-longevity (its repression extends lifespan), complete loss of function would be lethal. The annotations provided do not distinguish between gain- or loss-of-function contexts, making a directional prediction difficult without knowing the experimental perturbation direction.
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.
Advisor judgment
The model correctly identified rpc-1 as an RNA Polymerase III subunit and correctly understood the TORC1-Pol III signaling axis where Pol III repression extends lifespan. This mechanistic understanding is accurate and aligns with the anti-longevity classification (meaning the gene promotes aging/shortens lifespan, so its inhibition extends lifespan). However, the model predicted "unclear" rather than "anti_longevity." The reasoning was sound - the model understood that Pol III overactivity is anti-longevity - but it hedged too much on the directionality, citing uncertainty about gain vs. loss of function contexts. The ground truth is anti_longevity, which is consistent with the model's own mechanistic reasoning that "Pol III overactivity is anti-longevity." The model essentially had the right mechanistic understanding but failed to commit to the correct answer, instead choosing "unclear."
