MRPL38 (Mitochondrial Ribosomal Protein L38) is a nucleus-encoded protein component of the mitochondrial large ribosomal subunit (39S) essential for mitochondrial translation. As part of the mitoribosome, it facilitates the synthesis of core subunits of oxidative phosphorylation (OXPHOS) complexes, which drive ATP production. Human MRPL38 localizes to the mitochondrial matrix and interacts with other mitoribosomal proteins to maintain structural and functional integrity during mitochondrial protein synthesis.
The gene encoding MRPL38 is located on chromosome 17q25.3. Studies suggest its expression is tightly regulated due to the sensitivity of mitochondrial function to protein stoichiometry. Mutations or dysregulation of MRPL38 are linked to mitochondrial disorders, often presenting as multisystem deficiencies in energy-demanding tissues (e.g., brain, muscle). For instance, MRPL38 knockdown impairs mitoribosome assembly, reduces OXPHOS activity, and triggers metabolic stress, highlighting its critical role in cellular energy homeostasis.
Recombinant MRPL38 protein, typically expressed in bacterial or mammalian systems, is used to study its molecular interactions, structure-function relationships, and involvement in disease mechanisms. Its production enables antibody development, functional rescue experiments, and screening for therapeutic agents targeting mitochondrial translation defects. Ongoing research focuses on elucidating its specific role in ribosome biogenesis and potential as a biomarker for mitochondrial dysfunction.
