Predicted to enable NAD binding activity; NAD(P)+ transhydrogenase activity; and NADP binding activity. Predicted to be involved in several processes, including cell redox homeostasis; oxygen homeostasis; and positive regulation of hydrogen peroxide catabolic process. Located in mitochondrial inner membrane. Is expressed in several structures, including alimentary system; brain; musculature; respiratory system; and urinary system. Human ortholog(s) of this gene implicated in familial glucocorticoid deficiency. Orthologous to human NNT (nicotinamide nucleotide transhydrogenase).
