CLCN1 encodes the skeletal muscle voltage-gated chloride channel CLC-1, a major determinant of resting membrane conductance and action potential repolarization. By mediating chloride influx during repetitive firing, CLC-1 stabilizes sarcolemmal excitability and limits myofiber hyperexcitability, integrating with ion homeostasis processes that shape muscle contraction and fatigue resistance. CLCN1 dysfunction is strongly associated with myotonia congenita and related nondystrophic myotonic phenotypes, making it a key target for studying channel gating, muscle electrophysiology, and excitability-linked stress responses.
CLC-1 Double Nickase Plasmid (h) consists of a matched pair of plasmids engineered for high-specificity editing of the CLCN1 locus in human cell lines. Each plasmid expresses a Cas9 D10A nickase and a distinct sgRNA targeting opposite DNA strands within CLCN1. 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 CLCN1 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 CLCN1-disrupted clones.
