RCAN1 encodes DSCR 1 (Down syndrome critical region protein 1), an endogenous inhibitor and feedback regulator of the calcium/calmodulin-dependent phosphatase calcineurin (PPP3). By modulating calcineurin-dependent dephosphorylation and nuclear localization of NFAT transcription factors, DSCR 1 influences Ca2+-responsive gene expression programs that affect cell stress responses, apoptosis, and differentiation. RCAN1 is also linked to oxidative stress signaling and mitochondrial homeostasis, with reported impacts on neuronal and cardiovascular biology. Dysregulated RCAN1/DSCR 1 activity has been associated with altered NFAT signaling in conditions including Down syndrome–related phenotypes, neurodegeneration, and vascular dysfunction, supporting its use in mechanistic pathway studies.
DSCR 1 Double Nickase Plasmid (h) consists of a matched pair of plasmids engineered for high-specificity editing of the RCAN1 locus in human cell lines. Each plasmid expresses a Cas9 D10A nickase and a distinct sgRNA targeting opposite DNA strands within RCAN1. 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 RCAN1 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 RCAN1-disrupted clones.
