Solver output
TDP-1 is the C. elegans homolog of human TDP-43 (TARDBP), an RNA-binding protein that binds single-stranded RNA and chromatin and regulates RNA processing, splicing, and stability. In aging contexts, TDP-43/TDP-1 is well-known for its propensity to misfold and aggregate, contributing to proteotoxic stress and neurodegeneration. In C. elegans, loss-of-function of tdp-1 has been reported to extend lifespan, suggesting that the normal activity of TDP-1 is net detrimental to longevity, likely by promoting RNA dysregulation and protein aggregation under stress conditions. The aggregation-prone nature of TDP-1 and its role in stress granule dynamics links it to loss of proteostasis, a key hallmark of aging. Additionally, TDP-1 activity influences the DAF-16/FOXO and heat-shock response pathways, and its reduction can activate protective stress responses that extend lifespan.
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 predicted anti_longevity for tdp-1 in C. elegans. The mechanistic reasoning is solid: TDP-1 is the C. elegans homolog of human TDP-43, and loss-of-function extends lifespan, making it anti-longevity. The model correctly identifies proteotoxic stress, protein aggregation, and RNA dysregulation as key mechanisms. The mention of DAF-16/FOXO pathway involvement is plausible. The mechanism class of "cellular_senescence" is somewhat imprecise (proteostasis/proteotoxicity would be more accurate), but the overall reasoning is well-grounded. Confidence of 0.62 is appropriately moderate given the complexity.
