TP53BP2 encodes 53BP2 (also known as ASPP2), a proline-rich adaptor that binds the DNA-binding domain of p53 and modulates transcriptional programs governing apoptosis, cell-cycle control, and stress responses. Through interactions with p53 family members and components of cytoskeletal and junctional complexes, 53BP2 links genome surveillance to cell polarity and survival signaling. It participates in pathways connected to DNA damage responses, apoptotic signaling, and regulation of transcriptional outputs that influence cellular fitness. Dysregulation of TP53BP2 expression or function has been associated with altered p53 pathway activity and is studied in the context of tumor biology, genomic instability, and defects in programmed cell death.
53BP2 Double Nickase Plasmid (h) consists of a matched pair of plasmids engineered for high-specificity editing of the TP53BP2 locus in human cell lines. Each plasmid expresses a Cas9 D10A nickase and a distinct sgRNA targeting opposite DNA strands within TP53BP2. 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 TP53BP2 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 TP53BP2-disrupted clones.
