Provided below are ELISA kits targeting aspartyl-tRNA synthetase, a human protein encoded by DARS. This protein is 501 amino acids long, with a mass of 57.1 kDa, and is a member of the Class-II aminoacyl-tRNA synthetase family, Type 2 subfamily. 2 isoforms have been identified. This is reported to be a cytoplasmic protein. There is a noted implication in Hypomyelination with brainstem and spinal cord involvement and leg spasticity. Other alias names for this protein include: aspartate--tRNA ligase cytoplasmic, aspartate tRNA ligase 1 cytoplasmic, aspartyl-tRNA synthetase cytoplasmic, cell proliferation-inducing gene 40 protein, and aspartate tRNA ligase 1 cytoplasmic.
