NR5A1 encodes steroidogenic factor 1 (SF-1), an orphan nuclear receptor transcription factor that orchestrates adrenal and gonadal development and the differentiated function of steroidogenic cells. SF-1 regulates genes involved in steroid hormone biosynthesis, cholesterol transport, and reproductive axis signaling, integrating nuclear receptor networks and cAMP/PKA-responsive transcriptional programs. In human biology, altered NR5A1 activity is linked to disorders of sex development, adrenal insufficiency, and dysregulated steroidogenesis, making it a key node for studying endocrine lineage specification and hormone-regulated gene expression. SF-1 is therefore widely used as a molecular entry point to interrogate transcriptional control of steroidogenic pathways and developmental fate decisions in relevant cell models.
SF-1 Double Nickase Plasmid (h) consists of a matched pair of plasmids engineered for high-specificity editing of the NR5A1 locus in human cell lines. Each plasmid expresses a Cas9 D10A nickase and a distinct sgRNA targeting opposite DNA strands within NR5A1. 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 NR5A1 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 NR5A1-disrupted clones.
