FOXG1 encodes the forkhead box transcription factor BF-1, a key regulator of telencephalic patterning, neuronal progenitor proliferation, and timing of differentiation during human brain development. BF-1 shapes gene expression programs that influence neurogenesis and regional identity through transcriptional repression/activation, with downstream effects on cell-cycle control and lineage specification pathways. Disruption of FOXG1 dosage or function is strongly linked to neurodevelopmental phenotypes, including FOXG1 syndrome and broader autism spectrum and epileptic encephalopathy presentations. In cellular models, FOXG1 perturbation is used to study cortical progenitor competence, neuronal maturation, and network activity phenotypes relevant to developmental disorders.
BF-1 Double Nickase Plasmid (h) consists of a matched pair of plasmids engineered for high-specificity editing of the FOXG1 locus in human cell lines. Each plasmid expresses a Cas9 D10A nickase and a distinct sgRNA targeting opposite DNA strands within FOXG1. 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 FOXG1 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 FOXG1-disrupted clones.
