CENPH encodes centromere protein H (CENP-H), a core component of the inner kinetochore required for accurate chromosome segregation during mitosis. CENP-H participates in centromere/kinetochore assembly and stabilization, coordinating recruitment and maintenance of the CCAN network and supporting microtubule attachment and spindle checkpoint fidelity. Disruption of CENPH perturbs kinetochore function, leading to chromosome misalignment, lagging chromosomes, and aneuploidy, processes tightly linked to genome instability. Altered centromere and kinetochore pathway regulation, including CENPH-associated complexes, is frequently investigated in the context of proliferative defects and chromosomal instability phenotypes relevant to cancer biology and developmental disorders.
CENP-H Double Nickase Plasmid (h) consists of a matched pair of plasmids engineered for high-specificity editing of the CENPH locus in human cell lines. Each plasmid expresses a Cas9 D10A nickase and a distinct sgRNA targeting opposite DNA strands within CENPH. 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 CENPH 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 CENPH-disrupted clones.
