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. Human ortholog(s) of this gene implicated in combined oxidative phosphorylation deficiency 20. Orthologous to human VARS2 (valyl-tRNA synthetase 2, mitochondrial).
