NKX2-5 encodes Nkx-2.5, a homeobox transcription factor that coordinates cardiac lineage specification and morphogenesis by regulating gene programs controlling cardiomyocyte differentiation, conduction system development, and chamber formation. It functions within core cardiac transcriptional networks involving GATA factors, TBX proteins, and MEF2 to modulate enhancer activity and context-dependent chromatin states during embryogenesis and in adult myocardium. Dysregulated NKX2-5 activity or sequence variants are linked to congenital heart defects and arrhythmia-associated phenotypes, making it a widely used marker and mechanistic node for studying cardiogenesis and cardiac gene regulatory circuitry. In cell models, Nkx-2.5-dependent transcription influences sarcomere assembly, electrophysiological maturation, and stress-responsive remodeling pathways relevant to developmental and disease biology.
Nkx-2.5 Double Nickase Plasmid (h) consists of a matched pair of plasmids engineered for high-specificity editing of the NKX2-5 locus in human cell lines. Each plasmid expresses a Cas9 D10A nickase and a distinct sgRNA targeting opposite DNA strands within NKX2-5. 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 NKX2-5 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 NKX2-5-disrupted clones.
