CDX1 encodes the caudal type homeobox transcription factor Cdx1, a sequence-specific DNA-binding regulator that contributes to anterior–posterior patterning and intestinal epithelial differentiation. Cdx1 integrates developmental signaling inputs, including Wnt/β-catenin and retinoic acid–responsive programs, to shape lineage-specific transcriptional networks and regional identity. In adult tissues, CDX1 helps maintain epithelial homeostasis and influences proliferation–differentiation balance through transcriptional control of downstream target genes. Dysregulated CDX1 expression and altered CDX family activity have been associated with intestinal metaplasia and colorectal tumor biology, making it a useful locus for mechanistic studies of epithelial transformation and differentiation.
Cdx1 Double Nickase Plasmid (h) consists of a matched pair of plasmids engineered for high-specificity editing of the CDX1 locus in human cell lines. Each plasmid expresses a Cas9 D10A nickase and a distinct sgRNA targeting opposite DNA strands within CDX1. 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 CDX1 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 CDX1-disrupted clones.
