Human FFAR2 encodes GPR43, a short-chain fatty acid–sensing GPCR that is activated by acetate and propionate and couples primarily to Gαi/o and Gαq signaling. GPR43 regulates cAMP suppression, PLC-dependent calcium mobilization, and downstream MAPK and NF-κB-linked programs that shape chemotaxis, cytokine release, and barrier-related immune responses. Expression in myeloid lineages and epithelial contexts links FFAR2 to microbial metabolite sensing and metabolic–inflammatory crosstalk. Dysregulated GPR43 signaling has been associated with altered leukocyte recruitment and inflammatory phenotypes relevant to gastrointestinal inflammation, airway inflammation, and metabolic dysfunction.
GPR43 Double Nickase Plasmid (h) consists of a matched pair of plasmids engineered for high-specificity editing of the FFAR2 locus in human cell lines. Each plasmid expresses a Cas9 D10A nickase and a distinct sgRNA targeting opposite DNA strands within FFAR2. 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 FFAR2 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 FFAR2-disrupted clones.
