MAP1A encodes microtubule-associated protein 1A (MAP-1A), a high–molecular weight cytoskeletal regulator that stabilizes microtubules and contributes to axonal outgrowth, neurite branching, and maintenance of neuronal architecture. MAP-1A participates in microtubule dynamics and cytoskeleton-dependent intracellular transport, linking microtubule stability to vesicle trafficking and polarized neuronal morphology. Through these processes, MAP1A is commonly studied in pathways underlying neurodevelopment and synaptic organization. Perturbation of microtubule-associated proteins is broadly relevant to mechanisms of neuronal dysfunction and cytoskeletal dysregulation in neurological disease contexts.
MAP-1A Double Nickase Plasmid (h) consists of a matched pair of plasmids engineered for high-specificity editing of the MAP1A locus in human cell lines. Each plasmid expresses a Cas9 D10A nickase and a distinct sgRNA targeting opposite DNA strands within MAP1A. 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 MAP1A 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 MAP1A-disrupted clones.
