Solver output
Zmpste24 (CAAX prenyl protease 1 homolog) is a zinc metalloendopeptidase essential for the two-step proteolytic maturation of prelamin A into mature lamin A. It cleaves the farnesylated and carboxymethylated C-terminal tail of prelamin A, including removal of the 15-amino-acid peptide containing the farnesylcysteine. Loss of Zmpste24 causes accumulation of farnesylated prelamin A (progerin-like), which disrupts nuclear lamina integrity, impairs DNA damage response and repair, and leads to a progeroid syndrome in mice with dramatically shortened lifespan. By ensuring proper nuclear envelope architecture and genomic stability, normal Zmpste24 function is strongly pro-longevity. This places it squarely in the genomic instability hallmark, as nuclear lamina dysfunction caused by unprocessed prelamin A compromises DNA repair and chromatin organization.
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 Zmpste24 as pro_longevity with high confidence (0.92). The mechanistic reasoning is excellent and accurate: Zmpste24 is indeed required for the proteolytic processing of prelamin A into mature lamin A, and its loss leads to accumulation of farnesylated prelamin A, nuclear lamina dysfunction, impaired DNA damage response, and a progeroid syndrome with dramatically shortened lifespan in mice. The classification under genomic instability hallmark is appropriate. The key pathways identified are all correct and relevant. This is a well-reasoned, accurate prediction.
