Mitochondrial ribosomal protein L46 (MRPL46) is a nuclear-encoded component of the mitochondrial ribosome, specifically the large subunit (39S) of the mitochondrial ribosome (mitoribosome). As part of the mitoribosome, MRPL46 plays a critical role in the translation of mitochondrial DNA (mtDNA)-encoded proteins, which are essential for oxidative phosphorylation (OXPHOS) and cellular energy production. The mitochondrial ribosome is structurally and functionally distinct from its cytoplasmic counterpart, reflecting evolutionary adaptation to mitochondria's unique protein synthesis requirements. MRPL46. like other mitochondrial ribosomal proteins, ensures proper assembly and stability of the mitoribosome, facilitating accurate translation of mtDNA-encoded subunits of the electron transport chain complexes (I, III, IV, and V). Dysregulation or mutations in MRPL46 have been implicated in mitochondrial dysfunction, which is linked to metabolic disorders, neurodegenerative diseases, and cancer. Recombinant human MRPL46 protein is commonly produced in heterologous expression systems (e.g., E. coli or mammalian cells) for functional studies, structural analysis, and investigating its interactions within the mitoribosome. Research on MRPL46 also contributes to understanding mitochondrial translation mechanisms and potential therapeutic targets for mitochondrial-related pathologies. Its conserved regions across species highlight its evolutionary importance in maintaining mitochondrial proteostasis and cellular energy balance.
