Predicted to enable ATP binding activity and cysteine-tRNA ligase activity. Predicted to be involved in cysteinyl-tRNA aminoacylation. Predicted to act upstream of or within translation. Predicted to be located in mitochondrion. Predicted to be active in cytoplasm. Is expressed in metanephros. Human ortholog(s) of this gene implicated in combined oxidative phosphorylation deficiency 27. Orthologous to human CARS2 (cysteinyl-tRNA synthetase 2, mitochondrial).
