AP1B1 encodes the human β1-adaptin subunit of the adaptor protein 1 (AP-1) complex, a key coat adaptor that links cargo proteins to clathrin during vesicle budding at the trans-Golgi network and endosomes. By recognizing sorting motifs in cytosolic tails, AP-1 coordinates polarized trafficking, receptor recycling, and regulated delivery of membrane proteins that shape cell signaling and homeostasis. β1-Adaptin–dependent transport interfaces with endosomal sorting, lysosome biogenesis, and membrane protein turnover pathways that influence epithelial polarity and neuronal function. Disruption of AP1B1 has been associated with inherited disorders of intracellular trafficking, including neurodevelopmental phenotypes and multisystem disease features linked to defective cargo sorting.
β1-Adaptin Double Nickase Plasmid (h) consists of a matched pair of plasmids engineered for high-specificity editing of the AP1B1 locus in human cell lines. Each plasmid expresses a Cas9 D10A nickase and a distinct sgRNA targeting opposite DNA strands within AP1B1. 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 AP1B1 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 AP1B1-disrupted clones.
