DFNA5 Double Nickase Plasmid (h) | sc-410760-NIC | 20 µg | $410.00 |
DFNA5 (also known as GSDME) encodes a gasdermin family protein that links protease activation to membrane pore formation and programmed cell death. Upon caspase-3 cleavage, DFNA5 can drive a lytic, inflammatory cell-death program that intersects apoptosis-to-pyroptosis switching and influences cytokine release, membrane integrity, and innate immune signaling. DFNA5 activity has been implicated in epithelial stress responses and tumor biology, and germline variants are associated with autosomal dominant nonsyndromic hearing loss (DFNA5). These features make DFNA5 a useful node for studying regulated cell death, inflammatory signaling, and tissue-specific vulnerability mechanisms.
DFNA5 Double Nickase Plasmid (h) consists of a matched pair of plasmids engineered for high-specificity editing of the DFNA5 locus in human cell lines. Each plasmid expresses a Cas9 D10A nickase and a distinct sgRNA targeting opposite DNA strands within DFNA5. 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 DFNA5 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 DFNA5-disrupted clones.
