Predicted to enable aspartate-tRNA ligase activity; aspartate-tRNA(Asn) ligase activity; and protein homodimerization activity. Predicted to be involved in aspartyl-tRNA aminoacylation and mitochondrial asparaginyl-tRNA aminoacylation. Predicted to be located in nucleoplasm. Predicted to be active in mitochondrion. Orthologous to human DARS2 (aspartyl-tRNA synthetase 2, mitochondrial). [provided by Alliance of Genome Resources, Apr 2022]
