Provided below are ELISA kits targeting tyrosyl-tRNA synthetase, a human protein encoded by YARS. This protein is 528 amino acids long, with a mass of 59.1 kDa, and is a member of the Class-I aminoacyl-tRNA synthetase family. This is reported to be a cytoplasmic protein. It is also an enzyme classified as a(n) tyrosine-tRNA ligase. There is a noted implication in Charcot-Marie-Tooth disease, dominant, intermediate type, C. Other alias names for this protein include: tyrosine--tRNA ligase cytoplasmic, tyrosine tRNA ligase 1 cytoplasmic, tyrosyl--tRNA ligase, tyrosyl-tRNA synthetase cytoplasmic, TYRRS, YRS, and YTS.
