GJB1 encodes connexin 32 (Cx32), a gap junction channel protein that forms intercellular conduits for ions and small metabolites, enabling electrical and metabolic coupling between neighboring cells. Cx32 is prominent in myelinating Schwann cells and other epithelial tissues, where it supports tissue homeostasis by coordinating signaling, redox balance, and responses to injury. Through regulation of gap junctional intercellular communication, connexin 32 influences processes such as membrane excitability, cellular differentiation, and stress signaling pathways. Genetic alterations in GJB1 are strongly associated with inherited peripheral neuropathies, making it a key target for mechanistic studies of myelin maintenance and cell–cell communication defects.
connexin 32 Double Nickase Plasmid (h) consists of a matched pair of plasmids engineered for high-specificity editing of the GJB1 locus in human cell lines. Each plasmid expresses a Cas9 D10A nickase and a distinct sgRNA targeting opposite DNA strands within GJB1. 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 GJB1 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 GJB1-disrupted clones.
