IARS2 (Isoleucyl-tRNA Synthetase 2) is a nuclear-encoded mitochondrial enzyme crucial for protein synthesis within mitochondria. As a member of the aminoacyl-tRNA synthetase family, it catalyzes the attachment of isoleucine to its cognate tRNA (tRNA-Ile) during mitochondrial translation, ensuring fidelity in the production of mitochondrial-encoded proteins essential for oxidative phosphorylation (OXPHOS) and cellular energy metabolism. Mutations in the IARS2 gene have been linked to mitochondrial disorders, including Leigh syndrome, sensorineural hearing loss, and hepatopathy, underscoring its vital role in mitochondrial function.
Recombinant IARS2 protein is engineered for in vitro studies to investigate its enzymatic activity, structural properties, and interaction partners. Produced via heterologous expression systems (e.g., E. coli, mammalian cells), the recombinant protein retains post-translational modifications and functional domains necessary for tRNA recognition and aminoacylation. Researchers utilize it to dissect pathogenic mechanisms of IARS2 mutations, assess enzyme kinetics, and screen potential therapeutic compounds. Its applications extend to modeling mitochondrial diseases, studying tissue-specific isoforms, and exploring compensatory pathways in mitochondrial translation. By enabling precise biochemical characterization, recombinant IARS2 accelerates efforts to develop targeted therapies for mitochondrial disorders caused by IARS2 dysfunction.
