Predicted to enable ubiquitin protein ligase binding activity. Acts upstream of or within mitochondrial electron transport, ubiquinol to cytochrome c. Located in mitochondrion. Is expressed in several structures, including alimentary system; central nervous system; metanephros; respiratory system; and sensory organ. Human ortholog(s) of this gene implicated in Alzheimer's disease. Orthologous to human UQCRC1 (ubiquinol-cytochrome c reductase core protein 1). [provided by Alliance of Genome Resources, Apr 2022]
