LONP-1 is the mitochondrial Lon protease, an ATP-dependent serine protease that resides in the mitochondrial matrix. Its primary role is to degrade oxidatively damaged, misfolded, and unassembled mitochondrial proteins, thereby maintaining mitochondrial protein quality control. By clearing damaged proteins from the mitochondrial matrix, LONP-1 preserves mitochondrial function, supports the mitochondrial unfolded protein response (UPRmt), and limits the accumulation of dysfunctional mitochondria. Additionally, its single-stranded and sequence-specific DNA binding activities contribute to mitochondrial DNA (mtDNA) maintenance and replication fidelity. Loss of Lon protease function in model organisms leads to mitochondrial dysfunction, increased ROS, and shortened lifespan, while its activity is upregulated during stress responses that extend lifespan, placing it firmly in the pro-longevity category via mitochondrial proteostasis and integrity maintenance.

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 pro_longevity but the ground truth is anti_longevity. The model's reasoning about LONP-1's role in mitochondrial protein quality control is generally accurate in terms of its biochemical function, but it drew the wrong conclusion about its longevity influence. In C. elegans, lonp-1 is classified as anti_longevity, meaning its activity works against longevity (i.e., loss or reduction of lonp-1 may extend lifespan, or its overexpression shortens lifespan). The model incorrectly assumed that because LONP-1 maintains mitochondrial proteostasis, it must be pro-longevity. However, in C. elegans, mild mitochondrial stress (including impaired mitochondrial proteostasis) can actually activate hormetic responses that extend lifespan. The model was fairly confident (0.72) in its wrong answer and did not consider the possibility that lonp-1 could be anti_longevity through hormesis or other mechanisms.
