MAPRE1 encodes end-binding protein 1 (EB1), a core microtubule plus-end tracking protein that recognizes the GTP-tubulin cap and coordinates microtubule growth and stabilization. EB1 serves as a scaffold for +TIP networks, linking dynamic microtubules to kinetochores and the cell cortex to support spindle assembly, chromosome segregation, and directed cell migration. Through interactions with APC, CLIP proteins, and dynein/dynactin regulators, EB1 integrates microtubule dynamics with mitotic progression and cell polarity pathways. Dysregulated MAPRE1/EB1 function and expression have been associated with altered chromosomal stability and cytoskeletal remodeling observed in cancer-related cell biology studies.
EB1 Double Nickase Plasmid (h) consists of a matched pair of plasmids engineered for high-specificity editing of the MAPRE1 locus in human cell lines. Each plasmid expresses a Cas9 D10A nickase and a distinct sgRNA targeting opposite DNA strands within MAPRE1. 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 MAPRE1 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 MAPRE1-disrupted clones.
