Predicted to enable valine-tRNA ligase activity. Predicted to be involved in valyl-tRNA aminoacylation. Predicted to act upstream of or within tRNA aminoacylation for protein translation. Predicted to be active in cytosol. Is expressed in digestive system; immature eye; intermediate cell mass of mesoderm; nervous system; and somite. Orthologous to human VARS1 (valyl-tRNA synthetase 1).
