RPS3 encodes human Ribosomal Protein S3, a core component of the 40S small ribosomal subunit required for accurate translation initiation and mRNA decoding. Beyond its structural role in ribosome biogenesis, RPS3 has been linked to cellular stress responses and regulation of signaling pathways that coordinate protein synthesis with growth and DNA damage surveillance. Altered ribosomal protein homeostasis can perturb translational control and proteostasis, processes frequently implicated in tumor biology and other disorders characterized by dysregulated cell proliferation. As a result, RPS3 is widely studied in the context of ribosome function, stress-adaptive transcriptional programs, and mechanisms connecting translation to genome integrity.
Ribosomal Protein S3 Double Nickase Plasmid (h) consists of a matched pair of plasmids engineered for high-specificity editing of the RPS3 locus in human cell lines. Each plasmid expresses a Cas9 D10A nickase and a distinct sgRNA targeting opposite DNA strands within RPS3. 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 RPS3 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 RPS3-disrupted clones.
