Predicted to enable NADH dehydrogenase (ubiquinone) activity. Predicted to contribute to NADH dehydrogenase activity. Predicted to be involved in mitochondrial electron transport, NADH to ubiquinone; mitochondrial respiratory chain complex I assembly; and response to oxidative stress. Located in mitochondrion. Part of mitochondrial respiratory chain complex I. Is expressed in several structures, including early conceptus and oocyte. Human ortholog(s) of this gene implicated in nuclear type mitochondrial complex I deficiency 2. Orthologous to human NDUFS8 (NADH:ubiquinone oxidoreductase core subunit S8).
