ATF-5 Double Nickase Plasmid (h) | sc-416821-NIC | 20 µg | $410.00 |
ATF5 encodes activating transcription factor 5 (ATF-5), a basic leucine zipper transcription factor that coordinates gene expression programs linked to cellular stress adaptation, survival, and lineage maintenance. ATF-5 activity is commonly integrated with unfolded protein response and integrated stress response signaling, including PERK–eIF2α–ATF4 axis-dependent transcriptional regulation, and it can influence mitochondrial homeostasis and apoptosis-related transcriptional networks. In many cell systems, ATF-5 supports proliferation and resistance to metabolic or proteotoxic stress, making it relevant to studies of oncogenic signaling, differentiation states, and stress-driven transcriptional remodeling. Dysregulated ATF5 expression has been reported across multiple tumor contexts and neurobiological models, supporting investigation of its downstream targets and pathway dependencies in disease-associated phenotypes.
ATF-5 Double Nickase Plasmid (h) consists of a matched pair of plasmids engineered for high-specificity editing of the ATF5 locus in human cell lines. Each plasmid expresses a Cas9 D10A nickase and a distinct sgRNA targeting opposite DNA strands within ATF5. 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 ATF5 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 ATF5-disrupted clones.
