Predicted to enable tyrosine-tRNA ligase activity. Predicted to be involved in tyrosyl-tRNA aminoacylation. Predicted to act upstream of or within translation. Predicted to be located in cytosol and nuclear body. Is expressed in several structures, including alimentary system; brain; genitourinary system; respiratory system; and sensory organ. Human ortholog(s) of this gene implicated in Charcot-Marie-Tooth disease dominant intermediate C. Orthologous to human YARS1 (tyrosyl-tRNA synthetase 1).
