Maob Gene Summary [Rat]
Enables flavin adenine dinucleotide binding activity; identical protein binding activity; and oxidoreductase activity, acting on the CH-NH2 group of donors, oxygen as acceptor. Involved in several processes, including negative regulation of serotonin secretion; phenylethylamine catabolic process; and positive regulation of dopamine metabolic process. Located in dendrite; mitochondrial outer membrane; and neuronal cell body. Biomarker of Parkinson's disease and cholestasis. 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, Jul 2025]

Protein Domains
A protein domain is a distinct structural or functional region within a protein that can evolve, function, and exist independently of the rest of the protein chain. These domains in rat Maob often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
