背景信息

Mitochondrial Ribosomal Protein S12 (MRPS12) is a key component of the small subunit (28S) of the mitochondrial ribosome, which is essential for protein synthesis within mitochondria. Unlike cytosolic ribosomes, mitochondrial ribosomes translate a limited set of mRNAs encoding subunits of the oxidative phosphorylation (OXPHOS) complexes, critical for ATP production. MRPS12. encoded by the nuclear gene *MRPS12*, is synthesized in the cytoplasm and imported into mitochondria, where it integrates into the ribosome structure. It plays a structural role in stabilizing the ribosomal small subunit and may contribute to mRNA decoding or tRNA interactions during translation.

Dysfunction of MRPS12 is linked to mitochondrial disorders, often presenting with multi-system symptoms such as hypertrophic cardiomyopathy, muscle weakness, and neurological deficits due to impaired OXPHOS activity. Mutations in *MRPS12* are associated with altered ribosome assembly and reduced mitochondrial translation efficiency, leading to cellular energy deficits.

Recombinant MRPS12 protein is produced using heterologous expression systems (e.g., *E. coli* or mammalian cells) for functional studies. It serves as a tool to investigate mitochondrial translation mechanisms, disease pathogenesis, and therapeutic strategies targeting mitochondrial dysfunction. Tags (e.g., His-tag) are often added to facilitate purification. Research on MRPS12 enhances understanding of mitochondrial biology and its role in rare genetic diseases and aging-related metabolic conditions.
