BCL2L1 encodes the human Bcl-xS/L protein isoforms, central regulators of mitochondrial outer membrane permeabilization and intrinsic apoptosis. Bcl-xL is predominantly anti-apoptotic, restraining BAX/BAK activation and cytochrome c release, whereas Bcl-xS counteracts pro-survival signaling and can sensitize cells to apoptotic cues. Through integration with p53 stress responses and survival pathways such as PI3K–AKT and MAPK, BCL2L1 influences cell fate decisions, mitochondrial homeostasis, and adaptation to cellular stress. Dysregulated BCL2L1 expression and altered isoform balance are frequently linked to apoptosis evasion, therapy resistance, and tumor progression, making it a common target in mechanistic studies of cell death and survival.
Bcl-xS/L Double Nickase Plasmid (h) consists of a matched pair of plasmids engineered for high-specificity editing of the BCL2L1 locus in human cell lines. Each plasmid expresses a Cas9 D10A nickase and a distinct sgRNA targeting opposite DNA strands within BCL2L1. 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 BCL2L1 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 BCL2L1-disrupted clones.
