Predicted to enable alanine-tRNA ligase activity and aminoacyl-tRNA editing activity. Predicted to be involved in alanyl-tRNA aminoacylation. Predicted to be located in mitochondrion. Human ortholog(s) of this gene implicated in combined oxidative phosphorylation deficiency 8 and progressive leukoencephalopathy with ovarian failure. Is an ortholog of human AARS2 (alanyl-tRNA synthetase 2, mitochondrial).
