Solver output
bsk (basket) is the Drosophila ortholog of mammalian JNK (c-Jun N-terminal kinase), a stress-activated MAP kinase that phosphorylates the transcription factor Jun. While JNK signaling has context-dependent roles, its canonical activity as a JUN kinase drives pro-inflammatory and stress-response transcriptional programs. Chronic or elevated JNK/bsk activity promotes apoptosis, tissue degeneration, and inflammatory signaling, all of which are associated with accelerated aging phenotypes in Drosophila. Notably, reduced JNK signaling (loss-of-function of bsk) has been shown to extend lifespan in some contexts, while overactivation shortens it. The serine/threonine kinase activity of bsk phosphorylates downstream targets including AP-1 components (Jun/Fos), activating stress and immune pathways that, when chronically engaged, contribute to organismal aging. This places bsk's normal function in the pro-aging category, analogous to the well-established role of JNK pathway hyperactivation in promoting inflammation and cellular damage during aging.
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 predicted anti_longevity with 0.82 confidence, but the ground truth is pro_longevity. The model's reasoning is partially correct in identifying bsk as the Drosophila JNK ortholog and noting context-dependent roles, but it incorrectly concludes that bsk is anti-longevity. In Drosophila, JNK/bsk signaling is well-established as pro-longevity — activation of JNK signaling (e.g., through FOXO/dFOXO pathway interactions and stress resistance) extends lifespan. The model even acknowledges context-dependence but then incorrectly defaults to the anti-longevity conclusion. The mechanistic framing around chronic inflammation and tissue degeneration misses the key pro-longevity role of JNK in Drosophila, which involves stress resistance, autophagy induction, and FOXO activation. The model was confidently wrong.
