CENPE encodes CENP-E, a kinesin-like motor protein that localizes to kinetochores and drives chromosome congression and stable microtubule attachment during mitosis. By coordinating spindle checkpoint signaling and promoting accurate sister chromatid segregation, CENP-E supports genome integrity through the metaphase-to-anaphase transition. Dysregulated CENP-E function is associated with chromosomal instability and aneuploidy, linking this pathway to proliferative defects and cancer biology. Human CENP-E is therefore widely studied in cell-cycle regulation, kinetochore dynamics, and mechanisms that couple microtubule capture to checkpoint satisfaction.
CENP-E Double Nickase Plasmid (h) consists of a matched pair of plasmids engineered for high-specificity editing of the CENPE locus in human cell lines. Each plasmid expresses a Cas9 D10A nickase and a distinct sgRNA targeting opposite DNA strands within CENPE. 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 CENPE 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 CENPE-disrupted clones.
