Solver output
Rhomboid-7 (rho-7) is the Drosophila ortholog of the mitochondrial rhomboid protease PARL (presenilin-associated rhomboid-like). As a serine-type intramembrane endopeptidase, it localizes to the inner mitochondrial membrane where it processes key substrates involved in mitochondrial quality control, including the pro-apoptotic factor HtrA2/Omi and components of the mitochondrial fusion/fission machinery. Loss of rho-7 in Drosophila has been shown to cause mitochondrial dysfunction, increased oxidative stress, and neurodegeneration — phenotypes consistent with accelerated aging. By maintaining mitochondrial integrity and proteostasis within the organelle, rho-7 supports healthy mitochondrial function, a hallmark whose preservation is strongly associated with longevity. Its role in processing substrates that regulate mitochondrial dynamics and stress responses places it firmly in the pro-longevity category.
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 rho-7 in Drosophila melanogaster. The mechanistic reasoning is well-grounded: rho-7 is indeed the Drosophila ortholog of PARL, a mitochondrial intramembrane serine protease involved in mitochondrial quality control, and loss-of-function leads to mitochondrial dysfunction and neurodegeneration consistent with accelerated aging. The key pathways identified (PARL-HtrA2 axis, mitochondrial dynamics, intramembrane proteolysis) are all relevant and accurate. Confidence of 0.72 is appropriate given the specificity of the gene.
