Solver output
Tert encodes the catalytic reverse transcriptase subunit of telomerase, which uses its RNA-directed DNA polymerase activity to extend telomeric repeats at chromosome ends, directly counteracting telomere shortening with each cell division. In Mus musculus, loss of Tert leads to progressive telomere attrition across generations, resulting in premature aging phenotypes including stem cell exhaustion, tissue degeneration, and reduced lifespan, while overexpression or reactivation of Tert has been shown to extend healthspan and lifespan in mice. The telomerase holoenzyme assembles via Tert's protein homodimerization and telomerase RNA binding activities, and its template-free RNA nucleotidyltransferase activity contributes to de novo telomere synthesis. By maintaining telomere integrity, Tert preserves genomic stability, prevents replicative senescence, and sustains stem cell self-renewal capacity, all of which are pro-longevity functions.
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 identified Tert as pro_longevity with high confidence (0.93). The mechanistic reasoning is accurate and detailed: Tert encodes the catalytic subunit of telomerase, loss leads to telomere attrition and premature aging, while overexpression extends healthspan/lifespan in mice. The model correctly identified the telomere_attrition mechanism class and accurately described the molecular functions (RNA-directed DNA polymerase activity for telomere extension, protein homodimerization, telomerase RNA binding). The key pathways listed are all relevant and correct. This is a well-known gene in aging biology and the model's reasoning is thorough and accurate.
