**Background of Recombinant Human MRPL49 Protein**
The mitochondrial ribosomal protein L49 (MRPL49) is a component of the mitochondrial ribosome, specifically the large 39S subunit, which plays a critical role in mitochondrial protein synthesis. Mitochondrial ribosomes are responsible for translating respiratory chain subunits encoded by mitochondrial DNA (mtDNA), essential for oxidative phosphorylation (OXPHOS) and cellular energy production. MRPL49. encoded by the nuclear *MRPL49* gene, is synthesized in the cytoplasm and imported into mitochondria, where it integrates into the ribosome structure to support translational machinery.
Recombinant human MRPL49 protein is engineered using heterologous expression systems (e.g., *E. coli* or mammalian cells) to produce purified, biologically active forms for functional studies. Its structure and interactions are studied to elucidate mitochondrial translation mechanisms, particularly in diseases linked to mitochondrial dysfunction, such as metabolic disorders, neurodegenerative conditions, and cancer. Aberrant MRPL49 expression has been associated with disrupted ribosome assembly, impaired OXPHOS, and altered cell growth.
Research applications include investigating MRPL49’s role in mitochondrial ribosome biogenesis, exploring its potential as a biomarker, or developing models for mitochondrial diseases. Recombinant MRPL49 also serves as an antigen for antibody production or a tool for drug screening targeting mitochondrial translation pathways.
