CENPC encodes centromere protein C (CENP-C), a core inner kinetochore component that binds centromeric chromatin and helps organize the constitutive centromere-associated network required for stable microtubule attachment. CENP-C coordinates kinetochore assembly and spindle checkpoint signaling to ensure accurate chromosome congression and segregation during mitosis, linking centromere identity to cell-cycle progression. Disruption of CENP-C–dependent kinetochore architecture contributes to chromosome mis-segregation and aneuploidy, processes frequently associated with genome instability in proliferative disorders. Accordingly, CENP-C is widely studied in centromere biology, mitotic fidelity, and mechanisms that couple chromatin organization to chromosome inheritance.
CENP-C Double Nickase Plasmid (h) consists of a matched pair of plasmids engineered for high-specificity editing of the CENPC locus in human cell lines. Each plasmid expresses a Cas9 D10A nickase and a distinct sgRNA targeting opposite DNA strands within CENPC. 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 CENPC 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 CENPC-disrupted clones.
