LAMA4 encodes laminin α-4, a key extracellular matrix subunit that assembles into laminin heterotrimers within basement membranes and shapes cell–matrix adhesion and signaling. Laminin α-4 supports endothelial and smooth muscle interactions, contributes to vascular basement membrane organization, and influences migration, polarity, and survival through integrin- and dystroglycan-associated pathways that interface with focal adhesion signaling. Altered LAMA4 expression or basement membrane composition has been linked to dysregulated angiogenesis, inflammation, and remodeling in cardiometabolic and vascular pathologies, and is also observed in tumor microenvironment and stromal processes. As a matrix component, laminin α-4 provides a mechanistic entry point to study how extracellular cues regulate tissue architecture and barrier function.
Laminin α-4 Double Nickase Plasmid (h) consists of a matched pair of plasmids engineered for high-specificity editing of the LAMA4 locus in human cell lines. Each plasmid expresses a Cas9 D10A nickase and a distinct sgRNA targeting opposite DNA strands within LAMA4. 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 LAMA4 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 LAMA4-disrupted clones.
