Human GAP43 encodes growth associated protein 43 (GAP-43), a neuron-enriched, membrane-associated phosphoprotein that regulates axon outgrowth, growth cone motility, and synaptic plasticity. GAP-43 is a prominent substrate of protein kinase C and participates in cytoskeletal remodeling and vesicle/membrane dynamics through phosphorylation-dependent control of actin organization and signaling at the plasma membrane. Its expression is developmentally regulated and re-induced during neuronal injury responses, linking GAP-43 to pathways governing neurite regeneration and activity-dependent circuit refinement. Altered GAP-43 levels or phosphorylation state have been associated with neurodevelopmental and neurodegenerative phenotypes, making it a frequently studied marker and mechanistic node in neuronal connectivity and repair studies.
GAP-43 Double Nickase Plasmid (h) consists of a matched pair of plasmids engineered for high-specificity editing of the GAP43 locus in human cell lines. Each plasmid expresses a Cas9 D10A nickase and a distinct sgRNA targeting opposite DNA strands within GAP43. 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 GAP43 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 GAP43-disrupted clones.
