CYP1A2 encodes a hepatic cytochrome P450 monooxygenase that catalyzes oxidative metabolism of endogenous compounds and many xenobiotics, including caffeine and other aromatic substrates. As part of Phase I drug metabolism, CYP1A2 activity shapes bioactivation and clearance pathways by generating more polar metabolites and reactive intermediates that can influence oxidative stress and cellular redox homeostasis. Its expression is regulated by xenobiotic-sensing transcriptional programs, particularly aryl hydrocarbon receptor (AHR) signaling, linking environmental exposures to metabolic reprogramming. Interindividual variation in CYP1A2 function and regulation is widely studied for its impact on pharmacokinetic phenotypes, chemical susceptibility, and metabolism-associated liver biology.
CYP1A2 Double Nickase Plasmid (h) consists of a matched pair of plasmids engineered for high-specificity editing of the CYP1A2 locus in human cell lines. Each plasmid expresses a Cas9 D10A nickase and a distinct sgRNA targeting opposite DNA strands within CYP1A2. 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 CYP1A2 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 CYP1A2-disrupted clones.
