Human ANK2 encodes ankyrin B, a membrane adaptor protein that couples integral membrane proteins to the spectrin–actin cytoskeleton and organizes specialized membrane microdomains. Ankyrin B regulates localization and stability of ion channels and transporters, including Na⁺/K⁺-ATPase, Na⁺/Ca²⁺ exchanger, and voltage-gated channels, thereby shaping excitability, calcium handling, and membrane trafficking. Through these scaffolding functions it influences processes such as endocytic recycling, cytoskeletal remodeling, and polarized membrane organization in neurons and cardiomyocytes. Dysregulation or genetic variation in ANK2 has been linked to cardiac arrhythmia susceptibility and neurodevelopmental phenotypes, supporting its relevance in studies of electrophysiology, signaling, and cell architecture.
Ankyrin B Double Nickase Plasmid (h) consists of a matched pair of plasmids engineered for high-specificity editing of the ANK2 locus in human cell lines. Each plasmid expresses a Cas9 D10A nickase and a distinct sgRNA targeting opposite DNA strands within ANK2. 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 ANK2 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 ANK2-disrupted clones.
