Predicted to enable several functions, including kinase inhibitor activity; protein homodimerization activity; and tryptophan-tRNA ligase activity. Predicted to be involved in several processes, including regulation of angiogenesis; regulation of protein modification process; and tryptophanyl-tRNA aminoacylation. Predicted to be located in cytosol and nucleus. Predicted to be part of protein-containing complex. Predicted to be active in cytoplasm. Human ortholog(s) of this gene implicated in distal hereditary motor neuronopathy type 9. Orthologous to human WARS1 (tryptophanyl-tRNA synthetase 1).
