Gene Gene information from NCBI Gene database.
Entrez ID 55699
Gene name Isoleucyl-tRNA synthetase 2, mitochondrial
Gene symbol IARS2
Synonyms (NCBI Gene)
CAGSSSILERS
Chromosome 1
Chromosome location 1q41
Summary 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 prot
