Predicted to enable NADH dehydrogenase activity. Predicted to contribute to NADH dehydrogenase (ubiquinone) activity. Predicted to be involved in several processes, including mitochondrial electron transport, NADH to ubiquinone; mitochondrial respiratory chain complex I assembly; and substantia nigra development. Located in mitochondrion. Biomarker of Parkinsonism. Human ortholog(s) of this gene implicated in nuclear type mitochondrial complex I deficiency 8. Orthologous to human NDUFS3 (NADH:ubiquinone oxidoreductase core subunit S3). [provided by Alliance of Genome Resources, Apr 2022]
