Function

Aminoacyl-tRNA synthetases catalyze the aminoacylation of tRNA by their cognate amino acid. Because of their central role in linking amino acids with nucleotide triplets contained in tRNAs, aminoacyl-tRNA synthetases are thought to be among the first proteins that appeared in evolution. Two forms of tryptophanyl-tRNA synthetase exist, a cytoplasmic form, named WARS, and a mitochondrial form, named WARS2. This gene encodes the mitochondrial tryptophanyl-tRNA synthetase. Two alternative transcripts encoding different isoforms have been described.^[7] According to recent research, mutations of the mitochondrial form of the enzyme are believed to express two different neurological disorders: A subtype of autosomal recessive intellectual disability and a syndrome of severe infantile‐onset leukoencephalopathy.^[8]
