Predicted to enable NADH dehydrogenase (ubiquinone) activity and protease binding activity. Predicted to contribute to NADH dehydrogenase activity. Predicted to be involved in electron transport coupled proton transport; mitochondrial electron transport, NADH to ubiquinone; and mitochondrial respiratory chain complex I assembly. Located in mitochondrial inner membrane. Is expressed in several structures, including alimentary system; integumental system; respiratory system; retina; and urinary system. Human ortholog(s) of this gene implicated in nuclear type mitochondrial complex I deficiency 3. Orthologous to human NDUFS7 (NADH:ubiquinone oxidoreductase core subunit S7).
