RPSA encodes laminin receptor 1 (Laminin-R), a multifunctional cell-surface and ribosome-associated protein that binds laminin in the extracellular matrix and contributes to cell adhesion, migration, and cytoskeletal organization. Through laminin-dependent signaling, Laminin-R interfaces with pathways governing membrane organization, focal adhesion dynamics, and extracellular matrix–driven regulation of proliferation and survival. RPSA also participates in ribosome biogenesis and translation, linking extracellular cues to proteostasis and growth control. Dysregulated Laminin-R expression and altered laminin interactions have been associated with tumor cell invasion and metastatic phenotypes, making RPSA a frequent target in studies of cell–matrix communication and cancer biology.
Laminin-R Double Nickase Plasmid (h) consists of a matched pair of plasmids engineered for high-specificity editing of the RPSA locus in human cell lines. Each plasmid expresses a Cas9 D10A nickase and a distinct sgRNA targeting opposite DNA strands within RPSA. 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 RPSA 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 RPSA-disrupted clones.
