Predicted to be involved in mitochondrial electron transport, NADH to ubiquinone. Predicted to act upstream of or within several processes, including mitochondrion organization; multicellular organism aging; and respiratory electron transport chain. Predicted to be located in mitochondrion. Predicted to be part of mitochondrial respiratory chain complex I. Biomarker of arteriosclerosis. Human ortholog(s) of this gene implicated in cervical cancer and nuclear type mitochondrial complex I deficiency 9. Orthologous to human NDUFS6 (NADH:ubiquinone oxidoreductase subunit S6).
