**Mitochondrial Ribosomal Protein S14 (MRPS14)** is a key component of the small subunit (28S) of the mitochondrial ribosome, essential for mitochondrial protein synthesis. Encoded by nuclear DNA, it is synthesized in the cytoplasm and transported to the mitochondrial matrix, where it integrates into the ribosome structure. Mitochondrial ribosomes specialize in translating the 13 proteins encoded by mitochondrial DNA, all critical for oxidative phosphorylation (OXPHOS), the primary ATP-generating pathway. MRPS14 contributes to ribosome assembly, stability, and interaction with mitochondrial mRNA during translation.
Dysregulation or mutations in MRPS14 are implicated in mitochondrial dysfunction, linked to disorders like metabolic diseases, neurodegeneration, and cancer. Reduced MRPS14 expression may impair mitochondrial protein synthesis, compromising OXPHOS efficiency and leading to cellular energy deficits, oxidative stress, or apoptosis. Studies also suggest its role in tumorigenesis, as altered mitochondrial function can promote cancer cell survival or chemotherapy resistance.
Recombinant MRPS14 protein, produced via bacterial or mammalian expression systems, is widely used in functional studies to explore its structural role, disease mechanisms, or interactions with other mitochondrial components. Its applications extend to drug screening targeting mitochondrial translation or metabolic pathways. Research on MRPS14 enhances understanding of mitochondrial biology and its implications in health and disease.
