Provided below are ELISA kits targeting valyl-tRNA synthetase, a human protein encoded by VARS. This protein is 1264 amino acids long, with a mass of 140.5 kDa, and is a member of the Class-I aminoacyl-tRNA synthetase family. 2 isoforms have been identified. It is also an enzyme classified as a(n) valine-tRNA ligase. There is a noted implication in Neurodevelopmental disorder with microcephaly, seizures, and cortical atrophy. Other alias names for this protein include: valine--tRNA ligase, protein G7a, valine tRNA ligase 1 cytoplasmic, valyl-tRNA synthetase 2, NDMSCA, and VARS1.
