CTBP1 encodes the transcriptional corepressor CtBP1, a conserved regulator that links DNA-binding repressors to chromatin-modifying complexes to shape gene expression programs. CtBP1 participates in epigenetic control through interactions with histone deacetylases and other remodeling factors, influencing processes such as differentiation, apoptosis, and metabolic adaptation. As a NAD(H)-sensitive coregulator, CtBP1 integrates cellular redox state with transcriptional outputs and contributes to pathways including Wnt/β-catenin and TGF-β–associated transcriptional networks. Altered CTBP1 activity has been associated with dysregulated transcriptional repression in cancer biology and neurodevelopmental phenotypes, supporting its study in gene regulatory circuitry and disease-relevant cell states.
CtBP1 Double Nickase Plasmid (h) consists of a matched pair of plasmids engineered for high-specificity editing of the CTBP1 locus in human cell lines. Each plasmid expresses a Cas9 D10A nickase and a distinct sgRNA targeting opposite DNA strands within CTBP1. 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 CTBP1 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 CTBP1-disrupted clones.
