LAMB1 encodes laminin β-1, a core subunit of multiple laminin heterotrimers that assemble into basement membranes and organize extracellular matrix architecture. Through interactions with integrins, dystroglycan, and other matrix components, laminin β-1 supports cell adhesion, polarity, migration, and survival, influencing signaling nodes such as focal adhesion kinase and PI3K/AKT as well as cytoskeletal dynamics. In human tissues, LAMB1 contributes to epithelial and endothelial barrier properties and guides developmental processes including neurite outgrowth and tissue morphogenesis. Altered laminin composition or disrupted basement membrane assembly involving LAMB1 has been associated with congenital structural defects and can modulate invasive and fibrotic phenotypes in disease-relevant models.
Laminin β-1 Double Nickase Plasmid (h) consists of a matched pair of plasmids engineered for high-specificity editing of the LAMB1 locus in human cell lines. Each plasmid expresses a Cas9 D10A nickase and a distinct sgRNA targeting opposite DNA strands within LAMB1. 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 LAMB1 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 LAMB1-disrupted clones.
