CDKN1C encodes the cyclin-dependent kinase inhibitor p57 Kip2, a key negative regulator of G1/S progression that restrains CDK activity to enforce cell-cycle exit and support differentiation. As an imprinted gene predominantly expressed from the maternal allele, CDKN1C helps coordinate developmental growth programs and tissue homeostasis, intersecting with pathways governing proliferation, apoptosis, and lineage commitment. Altered CDKN1C expression or function is associated with dysregulated growth control and has been implicated in developmental overgrowth phenotypes and tumor biology, making it a useful node for studying cell-cycle checkpoints. In human cells, p57 Kip2 is also linked to senescence-like states and context-dependent responses to mitogenic signaling and stress.
p57 Kip2 Double Nickase Plasmid (h) consists of a matched pair of plasmids engineered for high-specificity editing of the CDKN1C locus in human cell lines. Each plasmid expresses a Cas9 D10A nickase and a distinct sgRNA targeting opposite DNA strands within CDKN1C. 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 CDKN1C 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 CDKN1C-disrupted clones.
