NSUN4 Double Nickase Plasmid (m) | sc-428269-NIC | 20 µg | $410.00 |
Nsun4 encodes NSUN4, a mitochondrial RNA cytosine-5 methyltransferase that methylates mt-rRNA and supports mitochondrial ribosome biogenesis and translation. Through coordination with mitochondrial transcription/translation machinery, NSUN4 helps maintain oxidative phosphorylation capacity and respiratory chain function, linking it to cellular energy metabolism and mitochondrial quality control. Perturbation of NSUN4 activity is expected to alter mitochondrial protein synthesis and bioenergetic signaling pathways that influence stress responses and cell fate decisions. As a result, Nsun4 is frequently studied in contexts where mitochondrial dysfunction contributes to disease-relevant phenotypes, including neurodegeneration, cardiometabolic imbalance, and developmental defects.
NSUN4 Double Nickase Plasmid (m) consists of a matched pair of plasmids engineered for high-specificity editing of the Nsun4 locus in mouse cell lines. Each plasmid expresses a Cas9 D10A nickase and a distinct sgRNA targeting opposite DNA strands within Nsun4. 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 Nsun4 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 Nsun4-disrupted clones.
