Predicted to enable heme binding activity; metal ion binding activity; and ubiquinol-cytochrome-c reductase activity. Predicted to be involved in mitochondrial electron transport, ubiquinol to cytochrome c and response to glucagon. Located in mitochondrion. Is expressed in several structures, including alimentary system; heart; integumental system; limb; and nervous system. Human ortholog(s) of this gene implicated in mitochondrial complex III deficiency nuclear type 6. Orthologous to human CYC1 (cytochrome c1). [provided by Alliance of Genome Resources, Apr 2022]
