FGFR4 encodes fibroblast growth factor receptor 4 (FGFR-4), a receptor tyrosine kinase that transduces signals from FGF ligands to regulate cell proliferation, survival, differentiation, and metabolic homeostasis. Upon ligand binding and dimerization, FGFR-4 activates downstream MAPK/ERK, PI3K/AKT, PLCγ/PKC, and STAT signaling pathways, coordinating transcriptional programs involved in tissue development and repair. Dysregulated FGFR4 signaling has been associated with altered growth-factor responsiveness, epithelial–mesenchymal signaling, and pathway rewiring observed across multiple cancer contexts and metabolic liver biology. FGFR-4 is also studied in receptor trafficking and phosphorylation dynamics, making it a useful node for dissecting receptor-driven network connectivity.
FGFR-4 Double Nickase Plasmid (h) consists of a matched pair of plasmids engineered for high-specificity editing of the FGFR4 locus in human cell lines. Each plasmid expresses a Cas9 D10A nickase and a distinct sgRNA targeting opposite DNA strands within FGFR4. 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 FGFR4 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 FGFR4-disrupted clones.
