Mitochondrial ribosomal protein L54 (MRPL54) is a component of the large subunit of the mitochondrial ribosome, which is essential for mitochondrial translation. Unlike cytosolic ribosomes, mitochondrial ribosomes synthesize a limited set of proteins critical for oxidative phosphorylation (OXPHOS), the process that generates cellular ATP. MRPL54. encoded by the nuclear gene *MRPL54*, is imported into mitochondria post-translationally and assembled into the 39S large ribosomal subunit. It plays a structural or catalytic role in ribosome biogenesis and function, though its precise molecular mechanisms remain less characterized compared to some other ribosomal proteins.
Recombinant MRPL54 protein is produced through heterologous expression systems (e.g., *E. coli* or mammalian cells) for functional and biochemical studies. Its recombinant form enables researchers to investigate its interactions within the ribosome, its role in mitochondrial protein synthesis, and potential links to mitochondrial disorders. Mutations or dysregulation of mitochondrial ribosomal proteins, including MRPL54. have been implicated in diseases such as mitochondrial encephalopathies, cardiomyopathies, and cancer, where OXPHOS defects are common. Recombinant MRPL54 also serves as a tool for antibody production, structural studies (e.g., cryo-EM), or screening for therapeutic compounds targeting mitochondrial translation.
Recent studies highlight MRPL54's possible involvement in cellular stress responses and apoptosis regulation, suggesting broader roles beyond ribosome assembly. However, research on MRPL54 remains nascent, with most data extrapolated from homologs or proteomic analyses. Its recombinant expression addresses challenges in isolating native mitochondrial proteins, facilitating mechanistic studies to bridge gaps in understanding mitochondrial gene expression and its pathologies.
