DARS is a symbol for the gene, Aspartyl-tRNA synthetase, in humans. Other names include: Aspartate--tRNA ligase, cytoplasmic; Cell proliferation-inducing gene 40 protein; Aspartate-tRNA ligase, cytoplasmic ; aspartate tRNA ligase 1, cytoplasmic; HBSL. The encoded protein is an enzyme with an amino acid length of 501 and a mass of 57.1 kDa. Other isoforms may exist. DARS is a member of the Class-II aminoacyl-tRNA synthetase family. This gene shares homology with other species, including: Fly, Mouse, Rat, E. coli, Zebrafish, Frog, Chicken.
