The Genesis of Mitochondrial Peptides

The mitochondria, often referred to as the "powerhouses of the cell," are renowned for their role in energy production through cellular respiration. However, recent discoveries have revealed a hidden dimension to these organelles: the capacity to encode and produce functional peptides. These mitochondrial-encoded peptides are distinct from proteins encoded by nuclear DNA that are subsequently imported into the mitochondria.作者：MKS Chan·被引用次数：2—These mitochondria‑targeted peptideshave emerged as promising therapeutic molecules in mitochondrial dysfunction and cancer. Concurrently, ... Instead, they are directly translated from the mitochondrial genome. This unique origin allows them to exert localized effects within or near the mitochondria, influencing a range of cellular processes.
