Predicted to enable flavin adenine dinucleotide binding activity; identical protein binding activity; and primary amine oxidase activity. Predicted to be involved in negative regulation of serotonin secretion; neurotransmitter catabolic process; and positive regulation of dopamine metabolic process. Located in mitochondrial inner membrane. Is expressed in several structures, including alimentary system; cardiovascular system; central nervous system; genitourinary system; and sensory organ. Human ortholog(s) of this gene implicated in Alzheimer's disease and Parkinson's disease. Orthologous to human MAOB (monoamine oxidase B). [provided by Alliance of Genome Resources, Apr 2022]
