MAGI-1 Double Nickase Plasmid (h) | sc-402283-NIC | 20 µg | $410.00 |
MAGI1 encodes MAGI-1, a membrane-associated guanylate kinase (MAGUK) scaffold protein concentrated at tight junctions and other cell–cell contact sites in epithelial and endothelial tissues. MAGI-1 organizes multiprotein complexes by coupling transmembrane junctional components to signaling effectors, helping coordinate polarity, barrier function, and junction assembly. Through its PDZ and WW domains, MAGI-1 interfaces with pathways linked to cytoskeletal remodeling and growth control, including crosstalk with PTEN/PI3K–AKT signaling and adhesion-dependent signaling networks. Dysregulation of MAGI1 expression or junctional localization has been associated with altered epithelial integrity and aberrant signaling in contexts relevant to cancer biology and barrier-related inflammatory processes.
MAGI-1 Double Nickase Plasmid (h) consists of a matched pair of plasmids engineered for high-specificity editing of the MAGI1 locus in human cell lines. Each plasmid expresses a Cas9 D10A nickase and a distinct sgRNA targeting opposite DNA strands within MAGI1. 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 MAGI1 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 MAGI1-disrupted clones.
