Also known as: MAO-B; 6330414K01Rik
Summary: Predicted to enable flavin adenine dinucleotide binding activity; identical protein binding activity; and oxidoreductase activity, acting on the CH-NH2 group of donors, oxygen as acceptor. Predicted to be involved in several processes, including negative regulation of serotonin secretion; phenylethylamine 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, Dec 2024]

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
