Human NMNAT1 encodes nicotinamide mononucleotide adenylyltransferase 1 (NMNAT-1), a nuclear enzyme that catalyzes the final step in NAD⁺ biosynthesis from NMN and ATP. By sustaining nuclear NAD⁺ pools, NMNAT-1 supports NAD⁺-dependent processes including PARP-mediated DNA damage responses, sirtuin-regulated chromatin dynamics, and transcriptional control linked to cellular stress and metabolism. NMNAT1 activity intersects with redox homeostasis and genome maintenance pathways that influence neuronal viability and energy balance. Genetic disruption of NMNAT1 has been associated with inherited retinal degeneration and related neurodegenerative phenotypes, making it a useful node for studying NAD⁺ biology in disease-relevant models.
NMNAT-1 Double Nickase Plasmid (h) consists of a matched pair of plasmids engineered for high-specificity editing of the NMNAT1 locus in human cell lines. Each plasmid expresses a Cas9 D10A nickase and a distinct sgRNA targeting opposite DNA strands within NMNAT1. 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 NMNAT1 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 NMNAT1-disrupted clones.
