Predicted to enable methyltransferase activity and oxidoreductase activity. Predicted to be involved in mitochondrial respiratory chain complex I assembly and peptidyl-arginine hydroxylation. Predicted to act upstream of or within methylation. Located in mitochondrion. Human ortholog(s) of this gene implicated in nuclear type mitochondrial complex I deficiency 16. Orthologous to human NDUFAF5 (NADH:ubiquinone oxidoreductase complex assembly factor 5). [provided by Alliance of Genome Resources, Apr 2022]
