ATF2 encodes activating transcription factor 2 (ATF-2), a bZIP transcription factor that forms homo- or heterodimers with AP-1 family members to regulate stimulus-responsive gene expression. ATF-2 is activated by phosphorylation downstream of stress-activated MAPK pathways, including JNK and p38, linking extracellular stress, DNA damage signaling, and inflammatory cues to transcriptional programs controlling proliferation, apoptosis, and differentiation. Through modulation of cytokine expression, cell-cycle regulators, and chromatin-associated processes, ATF-2 influences cellular adaptation to oxidative and genotoxic stress. Dysregulated ATF-2 activity has been implicated in oncogenic signaling, metastatic behavior, and altered immune or stress responses, making it relevant for mechanistic studies of tumor biology and stress pathway rewiring.
ATF-2 Double Nickase Plasmid (h) consists of a matched pair of plasmids engineered for high-specificity editing of the ATF2 locus in human cell lines. Each plasmid expresses a Cas9 D10A nickase and a distinct sgRNA targeting opposite DNA strands within ATF2. 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 ATF2 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 ATF2-disrupted clones.
