CYP17A1 Double Nickase Plasmid (h2) | sc-401918-NIC-2 | 20 µg | $410.00 |
CYP17A1 encodes cytochrome P450 17A1, a microsomal monooxygenase that catalyzes 17α-hydroxylase and 17,20-lyase reactions central to steroidogenesis. By converting pregnenolone and progesterone into 17-hydroxylated intermediates and subsequently generating dehydroepiandrosterone and androstenedione, CYP17A1 helps regulate flux through glucocorticoid and sex steroid biosynthetic pathways. Its activity integrates with electron transfer from P450 oxidoreductase in the endoplasmic reticulum and influences endocrine feedback circuits that control adrenal and gonadal hormone production. Dysregulated CYP17A1 function or expression is implicated in steroid hormone imbalance phenotypes and provides a mechanistic entry point for studying metabolism-linked signaling in endocrine-related disease models.
CYP17A1 Double Nickase Plasmid (h) consists of a matched pair of plasmids engineered for high-specificity editing of the CYP17A1 locus in human cell lines. Each plasmid expresses a Cas9 D10A nickase and a distinct sgRNA targeting opposite DNA strands within CYP17A1. 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 CYP17A1 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 CYP17A1-disrupted clones.
