GFRA1 encodes GFRα-1, a glycosylphosphatidylinositol-anchored co-receptor that binds glial cell line–derived neurotrophic factor (GDNF) and cooperates with the RET receptor tyrosine kinase to initiate downstream signaling. This receptor complex activates pathways including MAPK/ERK, PI3K/AKT, and PLCγ, regulating neuronal survival, differentiation, and axon guidance as well as kidney morphogenesis. GFRA1 signaling also contributes to maintenance of specific stem and progenitor cell states, linking ligand availability and receptor context to cell fate decisions. Dysregulated GDNF–GFRα-1–RET axis activity has been associated with neurodevelopmental phenotypes and oncogenic signaling contexts where RET pathway modulation is implicated.
GFRα-1 Double Nickase Plasmid (h) consists of a matched pair of plasmids engineered for high-specificity editing of the GFRA1 locus in human cell lines. Each plasmid expresses a Cas9 D10A nickase and a distinct sgRNA targeting opposite DNA strands within GFRA1. 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 GFRA1 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 GFRA1-disrupted clones.
