Provided below are ELISA kits targeting arginyl-tRNA synthetase, a human protein encoded by RARS. This protein is 660 amino acids long, with a mass of 75.4 kDa, and is a member of the Class-I aminoacyl-tRNA synthetase family. 2 isoforms have been identified. This is reported to be a cytoplasmic protein. It is also an enzyme classified as a(n) arginine-tRNA ligase. There is a noted implication in Leukodystrophy, hypomyelinating, 9. Other alias names for this protein include: arginine--tRNA ligase cytoplasmic, arginine tRNA ligase 1 cytoplasmic, arginyl-tRNA synthetase cytoplasmic, and DALRD1.
