RNF43 encodes a RING-type E3 ubiquitin ligase that functions as a key negative regulator of WNT/β-catenin signaling by ubiquitinating Frizzled receptors and promoting their endocytosis and turnover. Through this receptor-level control, RNF43 helps tune stem cell maintenance, epithelial homeostasis, and context-dependent proliferation and differentiation programs. Its activity is closely linked to the R-spondin/LGR axis and intersects with ubiquitin–proteasome system dynamics that shape membrane receptor availability. Dysregulation or loss-of-function alterations in RNF43 are frequently studied in relation to aberrant WNT pathway activation in gastrointestinal and pancreatic tumor biology and in models of epithelial transformation.
RNF43 Double Nickase Plasmid (h) consists of a matched pair of plasmids engineered for high-specificity editing of the RNF43 locus in human cell lines. Each plasmid expresses a Cas9 D10A nickase and a distinct sgRNA targeting opposite DNA strands within RNF43. 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 RNF43 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 RNF43-disrupted clones.
