Predicted to enable oxidoreductase activity. Predicted to be involved in mitochondrial electron transport, ubiquinol to cytochrome c. Located in mitochondrion. Is expressed in several structures, including alimentary system; cardiovascular system; hemolymphoid system; and liver. Used to study mitochondrial metabolism disease. Human ortholog(s) of this gene implicated in mitochondrial complex III deficiency. Orthologous to several human genes including UQCRFS1 (ubiquinol-cytochrome c reductase, Rieske iron-sulfur polypeptide 1). [provided by Alliance of Genome Resources, Apr 2022]
