Reasoning

mpk-1 is the C. elegans ortholog of ERK (extracellular signal-regulated kinase), the terminal MAP kinase in the RAS/MAPK signaling cascade. In C. elegans, the RAS-ERK/mpk-1 pathway is a key growth and proliferation-promoting axis that antagonizes the DAF-16/FOXO transcription factor, a central pro-longevity effector downstream of reduced insulin/IGF-1 signaling. Activation of mpk-1 promotes somatic and germline growth programs that are generally associated with shortened lifespan, and hyperactivation of RAS-MAPK signaling reduces longevity in multiple model organisms. Furthermore, mpk-1 activity in the germline promotes proliferation at the expense of longevity signals; loss of the germline extends lifespan in a manner partly dependent on reduced mpk-1 activity. Its serine/threonine kinase activity phosphorylates downstream targets that suppress stress resistance and pro-longevity transcriptional programs, placing it as an anti-longevity factor within the nutrient/growth sensing network.

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 mpk-1 as anti_longevity with 0.78 confidence, but the ground truth is pro_longevity. The model's reasoning follows a plausible but incorrect narrative: it frames mpk-1/ERK as a growth-promoting, DAF-16-antagonizing factor that shortens lifespan. In reality, mpk-1 in C. elegans has pro-longevity roles - for example, mpk-1 activity is required for the lifespan extension seen in germline-less animals (glp-1 mutants), and it plays roles in stress responses that promote longevity. The model's reasoning about germline proliferation is actually partially inverted - mpk-1 activity in the context of germline ablation promotes longevity rather than reducing it. The model was confidently wrong in both the final answer and the mechanistic explanation.
