NME1 encodes nm23-H1, a ubiquitously expressed nucleoside diphosphate kinase that regulates cellular nucleotide homeostasis and participates in signal transduction, cytoskeletal remodeling, and membrane trafficking. Beyond its enzymatic activity, nm23-H1 has been linked to control of cell motility, differentiation, and stress responses through interactions with small GTPase pathways and kinase networks. Altered NME1 expression and function has been associated with changes in invasive behavior and metastatic potential across multiple tumor contexts, and it is frequently studied in relation to proliferation and DNA damage–associated phenotypes. These features make NME1 a useful target for dissecting mechanisms of migration, genome stability, and pathway cross-talk in human cells.
nm23-H1 Double Nickase Plasmid (h) consists of a matched pair of plasmids engineered for high-specificity editing of the NME1 locus in human cell lines. Each plasmid expresses a Cas9 D10A nickase and a distinct sgRNA targeting opposite DNA strands within NME1. 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 NME1 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 NME1-disrupted clones.
