Human WEE1 encodes the Wee1 kinase, a central regulator of the G2/M checkpoint that restrains CDK1–cyclin B activity through inhibitory phosphorylation, thereby coordinating DNA replication completion with mitotic entry. Wee1 integrates signals from DNA damage and replication stress pathways and cooperates with ATR/CHK1 signaling to stabilize stalled replication forks and maintain genome integrity. Altered WEE1 function or expression is associated with dysregulated cell-cycle progression, replication stress tolerance, and chromosomal instability, processes frequently studied in cancer biology. As a checkpoint kinase, Wee1 is also relevant to investigations of apoptosis, mitotic catastrophe, and DNA repair pathway dependencies.
Wee 1 Double Nickase Plasmid (h) consists of a matched pair of plasmids engineered for high-specificity editing of the WEE1 locus in human cell lines. Each plasmid expresses a Cas9 D10A nickase and a distinct sgRNA targeting opposite DNA strands within WEE1. 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 WEE1 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 WEE1-disrupted clones.
