Predicted to enable calmodulin binding activity. Acts upstream of or within NADH dehydrogenase complex assembly. Located in mitochondrion. Is expressed in several structures, including alimentary system; liver lobe; lung; pectoral girdle and thoracic body wall musculature; and vibrissa. Human ortholog(s) of this gene implicated in nuclear type mitochondrial complex I deficiency 15. Orthologous to human NDUFAF4 (NADH:ubiquinone oxidoreductase complex assembly factor 4).
