AFDN encodes AF-6, a PDZ domain–containing adaptor protein concentrated at adherens and tight junctions where it links nectin family cell-adhesion receptors to the actin cytoskeleton. AF-6 coordinates junction assembly, epithelial and endothelial barrier integrity, and cell polarity, integrating cues from Rap1/Ras signaling and cytoskeletal remodeling pathways. Through its roles in contact inhibition, migration, and morphogenesis, AFDN is frequently studied in the context of altered tissue architecture and invasive phenotypes observed across multiple cancer types. Dysregulation of AF-6–dependent junctional signaling is also relevant to neurodevelopmental and cardiovascular biology where precise control of cell–cell adhesion and polarity is required.
AF-6 Double Nickase Plasmid (h) consists of a matched pair of plasmids engineered for high-specificity editing of the AFDN locus in human cell lines. Each plasmid expresses a Cas9 D10A nickase and a distinct sgRNA targeting opposite DNA strands within AFDN. 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 AFDN 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 AFDN-disrupted clones.
