Human ATN1 encodes atrophin-1, a nuclear transcriptional coregulator that associates with DNA-binding factors to modulate gene expression programs involved in neuronal development, differentiation, and chromatin-dependent repression. Atrophin-1 participates in transcriptional networks linked to Notch-related signaling and epigenetic control of neuronal fate, influencing cell-type–specific regulatory states in the central nervous system. Polyglutamine expansion in atrophin-1 is associated with dentatorubral-pallidoluysian atrophy (DRPLA), supporting its relevance to studies of neurodegeneration, protein homeostasis, and transcriptional dysregulation. ATN1 perturbation is therefore widely used to interrogate mechanisms of selective neuronal vulnerability and gene regulatory circuitry in human cellular models.
atrophin-1 Double Nickase Plasmid (h) consists of a matched pair of plasmids engineered for high-specificity editing of the ATN1 locus in human cell lines. Each plasmid expresses a Cas9 D10A nickase and a distinct sgRNA targeting opposite DNA strands within ATN1. 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 ATN1 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 ATN1-disrupted clones.
