Predicted to enable ATP binding activity; histidine-tRNA ligase activity; and protein homodimerization activity. Predicted to be involved in histidyl-tRNA aminoacylation and mitochondrial translation. Predicted to be located in cytoplasm. Predicted to be active in cytosol and mitochondrion. Human ortholog(s) of this gene implicated in Charcot-Marie-Tooth disease, axonal type 2W and Usher syndrome type 3B. Orthologous to human HARS1 (histidyl-tRNA synthetase 1).
