Predicted to enable cardiolipin binding activity and phosphatidic acid binding activity. Predicted to be involved in cristae formation; mitochondrial electron transport, ubiquinol to cytochrome c; and mitochondrial respiratory chain complex III assembly. Predicted to be located in cytosol; mitochondrion; and nucleoplasm. Predicted to be integral component of mitochondrial inner membrane. Human ortholog(s) of this gene implicated in mitochondrial complex III deficiency nuclear type 9. Orthologous to human UQCC3 (ubiquinol-cytochrome c reductase complex assembly factor 3).
