Human KMO (kynurenine 3-monooxygenase) is a flavin-dependent mitochondrial enzyme in the kynurenine pathway of tryptophan catabolism, catalyzing conversion of L-kynurenine to 3-hydroxykynurenine. By controlling flux toward downstream metabolites such as 3-hydroxyanthranilic acid and quinolinic acid, KMO influences cellular redox balance, NAD+ biosynthesis, and neuroimmune signaling. Altered KMO activity can shift levels of neuroactive and oxidative metabolites, linking this pathway to inflammation-associated processes and neurological disease mechanisms. KMO expression is also studied in contexts of metabolic stress and immune regulation where kynurenine pathway remodeling impacts cell-state transitions.
KMO CRISPR Activation Plasmid (h) provides a targeted, non-destructive approach to upregulating endogenous KMO expression without altering the underlying DNA sequence.
KMO CRISPR Activation Plasmid (h) is a three-plasmid synergistic activation mediator (SAM) system engineered for highly efficient, site-specific transcriptional upregulation of the KMO locus in human cell lines. The system is built around a catalytically inactive Cas9 (dCas9) carrying two inactivating mutations (D10A and N863A) that eliminate nuclease activity while preserving DNA binding. This dCas9 is fused to VP64, a potent transcriptional activator, and is co-expressed with a blasticidin resistance gene for selection. The second plasmid encodes the MS2-p65-HSF1 fusion protein, a secondary activator complex that works in concert with dCas9-VP64, alongside a hygromycin resistance gene. The third plasmid encodes a target-specific 20 nt sgRNA fused to two MS2 RNA aptamers that recruit the MS2-p65-HSF1 complex to the activation site, accompanied by a puromycin resistance gene. The three plasmids are delivered at a 1:1:1 mass ratio for balanced expression of all system components.
Once assembled at the target locus, the SAM complex binds within approximately 200 bp upstream of the KMO transcriptional start site, where VP64, p65, and HSF1 act in concert to recruit transcriptional machinery and drive upregulation of endogenous KMO expression. Unlike nuclease-active Cas9, dCas9 does not introduce double-strand breaks or modify the genomic sequence, preserving the native KMO locus and enabling the study of KMO-dependent transcriptional responses at the endogenous locus, making it a valuable tool for functional studies, target gene identification, and the modeling of KMO pathway restoration in tumor cells with silenced or reduced KMO expression.
