Solver output
TERT encodes the catalytic reverse transcriptase subunit of the telomerase holoenzyme, which uses its RNA-directed DNA polymerase activity to extend telomeric repeats at chromosome ends. By binding the telomerase RNA component (TERC) and synthesizing TTAGGG repeats onto telomere 3' overhangs, TERT directly counteracts replicative telomere shortening — the primary driver of telomere attrition. In zebrafish (Danio rerio), tert loss-of-function leads to progressive telomere shortening across generations, premature aging phenotypes, and reduced lifespan, mirroring findings in mice and humans. Maintenance of telomere length by TERT preserves genomic integrity, delays replicative senescence of stem and somatic cells, and sustains tissue renewal capacity, all of which are pro-longevity effects. Thus, the normal function of tert opposes the hallmark of telomere attrition and promotes organismal longevity.
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 pro_longevity for tert in Danio rerio with high confidence (0.93). The mechanistic reasoning is thorough and accurate: TERT is the catalytic subunit of telomerase, it extends telomeric repeats, and loss-of-function in zebrafish leads to progressive telomere shortening, premature aging, and reduced lifespan. The mechanism class (telomere_attrition) is appropriate, and the key pathways identified are all relevant. The reasoning correctly connects TERT function to genomic integrity, replicative senescence prevention, and tissue homeostasis. This is an excellent, well-reasoned prediction.
