TTX-1 is a homeobox transcription factor in C. elegans that binds DNA and regulates RNA polymerase II-dependent transcription. It is known to control thermosensory neuron (AFD) identity and thermotaxis behavior. While transcription factors can influence longevity through downstream targets (e.g., stress response, metabolic, or neuronal signaling genes), the molecular function annotations provided (DNA binding, RNA Pol II-specific transcription factor activity) are too general to infer a specific pro- or anti-longevity mechanism. TTX-1's primary characterized role is in neuronal cell fate specification rather than in canonical aging pathways such as insulin/IGF-1 signaling, proteostasis, or mitochondrial function. Without evidence linking its specific transcriptional targets to longevity-relevant pathways, a confident directional prediction cannot be made.

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 "unclear" while the ground truth is "pro_longevity." The model's reasoning is coherent and acknowledges TTX-1's role in thermosensory neuron identity (AFD neurons), but fails to connect this to longevity. TTX-1/AFD neurons are known to regulate thermotaxis and temperature-dependent lifespan in C. elegans — loss of ttx-1 function affects thermosensory signaling which influences longevity. The model correctly identified the thermosensory neuron identity role but didn't connect it to longevity regulation. The model was appropriately uncertain given the limited information provided, but the ground truth shows it is pro-longevity. Confidence was low (0.35), which is appropriate given the uncertainty, but the answer is still wrong.
