SART3 encodes SART-3, an RNA-binding protein that functions as a U4/U6 snRNP recycling factor and supports spliceosome reassembly during pre-mRNA splicing. By coordinating snRNP dynamics and spliceosomal component trafficking, SART-3 contributes to transcriptome integrity, cell-cycle progression, and cellular stress responses. Altered SART3 expression or spliceosomal regulation has been associated with aberrant RNA processing programs observed in cancer and immune-related contexts, making it a useful node for studying how splicing perturbations reshape gene expression networks.
SART-3 Double Nickase Plasmid (h) consists of a matched pair of plasmids engineered for high-specificity editing of the SART3 locus in human cell lines. Each plasmid expresses a Cas9 D10A nickase and a distinct sgRNA targeting opposite DNA strands within SART3. 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 SART3 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 SART3-disrupted clones.
