Provided below are ELISA kits targeting lysyl-tRNA synthetase, a human protein encoded by KARS. This protein is 597 amino acids long, with a mass of 68 kDa, and is a member of the Class-II aminoacyl-tRNA synthetase family. 2 isoforms have been identified. This is reported to be a cytoplasmic, nuclear, mitochondrial, membrane and secreted protein. There is a noted implication in Charcot-Marie-Tooth disease, recessive, intermediate type, B. Other alias names for this protein include: lysine--tRNA ligase, lysRS, lysine tRNA ligase, CMTRIB, KARS1, KARS2, and KRS.
