NCOA1 encodes steroid receptor coactivator-1 (SRC-1), a transcriptional coactivator that bridges ligand-activated nuclear receptors and other transcription factors to chromatin-modifying complexes. SRC-1 coordinates histone acetylation and remodeling to regulate gene programs involved in hormone response, proliferation, metabolism, and differentiation. It participates in signaling networks driven by estrogen, androgen, progesterone, glucocorticoid, and thyroid hormone receptors, and intersects with pathways such as MAPK/ERK and PI3K/AKT via phosphorylation-dependent coactivator dynamics. Dysregulated NCOA1/SRC-1 expression or activity has been associated with altered endocrine signaling and transcriptional reprogramming observed across multiple cancers and metabolic and inflammatory contexts, supporting its use as a mechanistic node in gene regulation studies.
SRC-1 Double Nickase Plasmid (h) consists of a matched pair of plasmids engineered for high-specificity editing of the NCOA1 locus in human cell lines. Each plasmid expresses a Cas9 D10A nickase and a distinct sgRNA targeting opposite DNA strands within NCOA1. 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 NCOA1 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 NCOA1-disrupted clones.
