MitochondrialpeptideSS-31 The intricate world of cellular biology often holds the keys to understanding complex physiological processes, and the role of mitochondria within this landscape is paramount. These organelles, famously known as the "power generators" of cells, not only produce energy but are also increasingly recognized for their involvement in a variety of cellular functions through the production of mitochondria-derived peptides (MDPs).作者：MP Siegel·2013·被引用次数：224—A single treatment with themitochondrial targeted peptide SS-31restores in vivo mitochondrial energetics to young levels in aged mice after only one hour. These fascinating small peptides hidden in the mitochondrial DNA are emerging as critical regulators of metabolism, cellular health, and even the aging process.

Mitochondria themselves are dynamic entities, and their function is intrinsically linked to mitochondrial energetics and the production of energy currency through processes like oxidative phosphorylation. However, a more nuanced picture is emerging, highlighting that mitochondria harbor a conserved proteolytic system capable of degrading polypeptides, suggesting a more complex internal environment than previously understood. This understanding is paving the way for groundbreaking research into mitochondria-derived peptides (MDPs)effects and mechanisms related to stress, metabolism and aging. These translated peptides encoded by short open reading frames (sORFs), particularly those identified within mitochondrial (mt) DNA genes, are proving to be potent signaling molecules. Studies have even identified 270 peptides that are exported from mitochondria, underscoring the breadth of their potential roles.

Among the most studied mitochondrial peptides is MOTS-c, a 16-amino-acid peptide encoded in the mitochondrial genome.作者：B Miller·2022·被引用次数：102—Mitochondria contain DNA with small open reading frames (sORFs) that encode functional microproteins, calledmitochondria-derived peptides (MDPs) ... Discovered as a peptide encoded by the short open reading frame of the mitochondrial 12S rRNA gene, MOTS-c has garnered significant attention for its multifaceted actions.
