Monoamine oxidase B (MAO-B), encoded by the human MAOB gene, is a flavin-dependent enzyme localized primarily to the outer mitochondrial membrane where it catalyzes oxidative deamination of monoamine neurotransmitters and dietary amines. This reaction contributes to dopamine and phenethylamine catabolism and produces hydrogen peroxide, linking MAO-B activity to cellular redox balance, mitochondrial stress responses, and downstream antioxidant pathways. MAO-B function intersects with neurotransmitter turnover and oxidative metabolism in neural and peripheral tissues, making MAOB a commonly studied target in models of neurodegeneration, neuroinflammation, and age-associated changes in mitochondrial function. Altered MAOB expression or MAO-B activity is also used to probe mechanisms of reactive oxygen species signaling, metabolic reprogramming, and cell-type–specific monoaminergic regulation.
MAO-B Double Nickase Plasmid (h) consists of a matched pair of plasmids engineered for high-specificity editing of the MAOB locus in human cell lines. Each plasmid expresses a Cas9 D10A nickase and a distinct sgRNA targeting opposite DNA strands within MAOB. When directed to adjacent sites on opposite DNA strands, the two nickases generate offset single-strand nicks that together produce a staggered double-strand break, requiring coordinated on-target activity from both guides. The resulting DNA break is resolved by endogenous cellular repair pathways, most commonly through non-homologous end joining (NHEJ), leading to insertions or deletions that disrupt MAOB function. By requiring dual sgRNA engagement at the target locus, the double nicking approach enhances editing specificity and provides a complementary CRISPR strategy for applications where additional control over targeting precision is desired.
To support efficient identification of edited cells, one plasmid encodes GFP for fluorescent visualization of transfected populations, while the companion plasmid carries a puromycin resistance gene for antibiotic selection. Together, these features support efficient enrichment of co-transfected populations and simplify the validation of MAOB-disrupted clones.
