RPS6A

solver

{
  "reasoning": "RPS6A encodes the 40S ribosomal small subunit protein eS6, a well-known downstream phosphorylation target of the TOR (Target of Rapamycin) / S6 Kinase (Sch9 in yeast) signaling axis. As a structural constituent of the ribosome, it directly supports translational capacity and ribosome biogenesis, both of which are upregulated by active TORC1 signaling. Elevated TORC1/S6K activity and increased ribosomal output are strongly associated with reduced lifespan in yeast and other organisms; conversely, reducing ribosomal protein gene dosage (including RPS6) extends chronological and replicative lifespan in S. cerevisiae. The pro-growth, pro-translation function of RPS6A thus opposes longevity by sustaining high anabolic flux downstream of nutrient-sensing pathways. Deletion or reduction of RPS6A mimics partial TOR inhibition, which is a canonical longevity intervention.",

  "notes": "The model correctly predicted anti_longevity for RPS6A with high confidence (0.72). The mechanistic reasoning is excellent and well-grounded: RPS6A encodes a 40S ribosomal protein that is a downstream target of TOR/S6K signaling, and deletion of ribosomal protein genes (including RPS6) is known to extend lifespan in yeast by mimicking partial TOR inhibition. The model correctly identifies that the pro-growth, pro-translation function of RPS6A opposes longevity. The mechanism class of \"deregulated_nutrient_sensing\" is appropriate given the TOR/S6K connection. The reasoning is detailed, accurate, and well-supported by the literature on yeast aging.",
