Mitochondrial and cellular proteins

The term Mitochondrial and cellular proteins refers to the vast and diverse collection of proteins residing within the mitochondria and the broader cellular environment, rather than a single, specific therapeutic target. Mitochondria alone contain approximately 1,100 to 1,500 distinct proteins that are essential for ATP production via oxidative phosphorylation, the regulation of apoptosis, and various metabolic pathways such as the citric acid cycle (Rath et al., 2021, Nucleic Acids Res). Cellular proteins encompass the entire proteome, including enzymes, receptors, and structural proteins that maintain cell integrity and function. Because this term aggregates thousands of different molecules with widely varying functions, it does not meet the criteria for a specific drug target in modern pharmacology. Drug development typically focuses on individual proteins or specific complexes to achieve selectivity and minimize off-target effects (Santos et al., 2017, Nat Rev Drug Discov).
