Human POR encodes cytochrome P450 oxidoreductase (CYPOR), an essential flavoprotein that transfers electrons from NADPH to microsomal cytochrome P450 enzymes in the endoplasmic reticulum. This activity supports xenobiotic metabolism, steroid hormone biosynthesis, fatty acid oxidation, and broader redox homeostasis by enabling CYP-dependent monooxygenase reactions. POR function therefore interfaces with drug metabolism pathways and endocrine steroidogenic networks that influence cellular stress responses and metabolic phenotypes. Genetic or functional perturbation of POR is relevant to disorders of steroidogenesis and variable pharmacogenomic responses, making it a useful target for mechanistic studies in hepatocyte-like and steroidogenic cell models.
CYPOR Double Nickase Plasmid (h) consists of a matched pair of plasmids engineered for high-specificity editing of the POR locus in human cell lines. Each plasmid expresses a Cas9 D10A nickase and a distinct sgRNA targeting opposite DNA strands within POR. 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 POR 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 POR-disrupted clones.
