TFAP2A encodes the transcription factor AP-2α, a sequence-specific DNA-binding protein that coordinates gene expression programs during neural crest development, epidermal differentiation, and craniofacial morphogenesis. AP-2α regulates promoters and enhancers controlling cell-cycle progression, cell–cell adhesion, and epithelial lineage specification, integrating cues from developmental signaling pathways such as WNT and retinoic acid–responsive networks. Dysregulated TFAP2A activity has been linked to congenital developmental disorders and altered transcriptional states in cancer, where changes in AP-2α-dependent regulatory circuits can impact proliferation and differentiation. These properties make TFAP2A a useful locus for dissecting transcriptional control of lineage decisions and epithelial biology in human cell models.
AP-2α Double Nickase Plasmid (h) consists of a matched pair of plasmids engineered for high-specificity editing of the TFAP2A locus in human cell lines. Each plasmid expresses a Cas9 D10A nickase and a distinct sgRNA targeting opposite DNA strands within TFAP2A. 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 TFAP2A 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 TFAP2A-disrupted clones.
