Background Information

KARS (lysyl-tRNA synthetase) is a gene that encodes an enzyme critical for protein synthesis, specifically responsible for attaching the amino acid lysine to its corresponding transfer RNA (tRNA) in both the cytoplasm and mitochondria. This enzyme plays a crucial role in the process of aminoacylation, which is essential for accurate protein translation from mRNA sequences. Mutations in the KARS gene have been associated with a variety of neurological and systemic disorders, reflecting the enzyme's importance in cellular function.
