Predicted to enable fatty-acyl-CoA binding activity; medium-chain-acyl-CoA dehydrogenase activity; and very-long-chain-acyl-CoA dehydrogenase activity. Predicted to be involved in long-chain fatty acid metabolic process; medium-chain fatty acid metabolic process; and mitochondrial respiratory chain complex I assembly. Located in mitochondrion. Is expressed in several structures, including alimentary system; genitourinary system; nervous system; respiratory system; and sensory organ. Human ortholog(s) of this gene implicated in nuclear type mitochondrial complex I deficiency 20. Orthologous to human ACAD9 (acyl-CoA dehydrogenase family member 9).
