Predicted to enable 4 iron, 4 sulfur cluster binding activity; electron-transferring-flavoprotein dehydrogenase activity; and ubiquinone binding activity. Involved in response to oxidative stress. Located in mitochondrial inner membrane. Is expressed in several structures, including alimentary system; cardiovascular system; genitourinary system; integumental system; and nervous system. Human ortholog(s) of this gene implicated in multiple acyl-CoA dehydrogenase deficiency. Orthologous to human ETFDH (electron transfer flavoprotein dehydrogenase).
