Human RAPGEF3 encodes Epac (exchange protein directly activated by cAMP), a guanine nucleotide exchange factor that preferentially activates Rap1 and Rap2 to couple cAMP signals to small GTPase–dependent responses. Epac regulates integrin-mediated adhesion, endothelial barrier function, vesicle trafficking, and cell junction remodeling, integrating inputs from GPCR signaling into cytoskeletal and membrane dynamics. Through Rap-driven control of MAPK and PI3K-related signaling nodes, RAPGEF3 influences proliferation, migration, and secretion across multiple cell types. Dysregulated cAMP–Epac–Rap signaling has been implicated in cardiovascular and metabolic phenotypes and is studied in contexts including inflammation, fibrosis, and cancer-associated changes in adhesion and invasiveness.
Epac Double Nickase Plasmid (h) consists of a matched pair of plasmids engineered for high-specificity editing of the RAPGEF3 locus in human cell lines. Each plasmid expresses a Cas9 D10A nickase and a distinct sgRNA targeting opposite DNA strands within RAPGEF3. 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 RAPGEF3 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 RAPGEF3-disrupted clones.
