[Abstract] Mitochondria serve as the central hub of cellular energy metabolism. Beyond generating ATP via oxidative
phosphorylation to sustain vital activities,they participate in regulating material metabolism,apoptosis,signal transduction,and
reactive oxygen species homeostasis. Maintenance of mitochondrial homeostasis is indispensable for preserving intracellular
microenvironmental stability and the physiological function of organs. LON protease 1(LONP1)is an ATP⁃dependent serine protease
encoded by the nuclear gene LONP1(PRSS15),which is highly conserved in evolution and plays various biological functions. It is
mainly localized in the mitochondrial matrix,with functions of clearing misfolded and oxidatively modified proteins,stabilizing
mitochondrial DNA(mtDNA),and being a molecular chaperone. To date,there is growing evidence that LONP1,through its regulation
of mitochondrial quality and energy homeostasis,is involved in development,aging,and various diseases. This article reviews the
biological characteristics,structure,and function of LONP1,as well as the advances of LONP1 in embryonic development,aging,
cancer,and various diseases.
