SRA1 encodes steroid receptor RNA activator 1 (SRA), a multifunctional RNA and protein co-regulator that modulates transcriptional programs controlled by nuclear receptors and other transcription factors. SRA participates in chromatin remodeling and assembly of transcriptional complexes that influence hormone-responsive gene expression, coupling steroid signaling with broader epigenetic and RNA-mediated regulatory processes. Through these activities, SRA1 is linked to pathways governing cell differentiation, metabolic regulation, and stress-responsive transcriptional outputs. Dysregulated SRA1/SRA expression has been reported across hormone-related and proliferative disease contexts, supporting its use as a mechanistic target for dissecting transcriptional network perturbations.
SRA Double Nickase Plasmid (h) consists of a matched pair of plasmids engineered for high-specificity editing of the SRA1 locus in human cell lines. Each plasmid expresses a Cas9 D10A nickase and a distinct sgRNA targeting opposite DNA strands within SRA1. 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 SRA1 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 SRA1-disrupted clones.
