Human FOSL2 encodes Fra2, an AP-1 family bZIP transcription factor that heterodimerizes with JUN proteins to regulate stimulus-responsive gene expression. Fra2 integrates MAPK/ERK and JNK signaling to control proliferation, differentiation, extracellular matrix remodeling, and inflammatory transcriptional programs. Through AP-1–dependent regulation of cytokines, metalloproteinases, and EMT-associated genes, altered FOSL2 activity has been linked to oncogenic signaling, fibrosis-related pathways, and immune dysregulation in multiple tissue contexts. Fra2 is therefore widely used as a molecular node for studying transcriptional network rewiring downstream of growth factors, stress cues, and developmental signals.
Fra2 Double Nickase Plasmid (h) consists of a matched pair of plasmids engineered for high-specificity editing of the FOSL2 locus in human cell lines. Each plasmid expresses a Cas9 D10A nickase and a distinct sgRNA targeting opposite DNA strands within FOSL2. 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 FOSL2 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 FOSL2-disrupted clones.
