RPL34B

solver

{
  "reasoning": "RPL34B encodes a structural component of the 60S ribosomal large subunit (eL34), directly contributing to ribosome biogenesis and translational capacity. In yeast, ribosome biogenesis is a major downstream effector of the TOR (Target of Rapamycin) nutrient-sensing pathway; high ribosomal activity is associated with increased TOR signaling and reduced lifespan. Deletion of large-subunit ribosomal protein genes, including RPL34B, has been shown in genome-wide screens to extend chronological and replicative lifespan in S. cerevisiae, consistent with the idea that reducing translational output mimics caloric restriction and dampens TOR activity. The structural role of eL34 in assembling functional 60S subunits means its normal function sustains high ribosome levels, promoting anabolic signaling that opposes longevity. This places RPL34B in the deregulated nutrient-sensing hallmark, specifically through TOR-driven ribosome biogenesis.",

  "notes": "The model correctly predicted anti_longevity for RPL34B. The mechanistic reasoning is sound and well-articulated: RPL34B encodes a 60S ribosomal structural protein, and deletion of ribosomal protein genes in yeast is well-established to extend lifespan by reducing translational output and mimicking caloric restriction via TOR pathway dampening. The mechanism class of \"deregulated_nutrient_sensing\" is appropriate given the TOR-ribosome biogenesis connection. The confidence of 0.72 is reasonable. Overall, this is a high-quality, accurate prediction with correct mechanistic reasoning.",
