Predicted to enable enzyme binding activity and protein-arginine omega-N symmetric methyltransferase activity. Predicted to be involved in mitochondrial respiratory chain complex I assembly and peptidyl-arginine methylation, to symmetrical-dimethyl arginine. Predicted to act upstream of or within methylation. Located in mitochondrion. Is expressed in brain. Orthologous to human NDUFAF7 (NADH:ubiquinone oxidoreductase complex assembly factor 7). [provided by Alliance of Genome Resources, Apr 2022]
