Predicted to enable NADH binding activity; aldehyde dehydrogenase (NAD+) activity; and identical protein binding activity. Predicted to be involved in several processes, including behavioral response to ethanol; cellular detoxification of aldehyde; and intrinsic apoptotic signaling pathway in response to oxidative stress. 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 several diseases, including alcohol use disorder; artery disease (multiple); diabetes mellitus (multiple); diabetic neuropathy; and liver disease (multiple). Orthologous to human ALDH2 (aldehyde dehydrogenase 2 family member). [provided by Alliance of Genome Resources, Apr 2022]
