Predicted to enable tyrosine-tRNA ligase activity. Predicted to be involved in tRNA aminoacylation. Predicted to act upstream of or within tyrosyl-tRNA aminoacylation. Predicted to be active in cytosol and mitochondrion. Human ortholog(s) of this gene implicated in myopathy, lactic acidosis, and sideroblastic anemia 2. Orthologous to human YARS2 (tyrosyl-tRNA synthetase 2).
