Lasp1 encodes LIM and SH3 protein 1 (LASP-1), an actin-binding adaptor enriched at focal adhesions, lamellipodia, and membrane ruffles where it helps coordinate cytoskeletal remodeling and cell motility. Through interactions with actin-associated proteins and signaling complexes, LASP-1 contributes to adhesion dynamics, migration, and mechanotransduction pathways linked to extracellular matrix engagement. In mouse systems, Lasp1 activity is frequently examined in contexts of epithelial–mesenchymal behaviors, wound repair, and tissue remodeling where changes in adhesion and invasion programs are prominent. Altered LASP-1 expression and localization have been associated with dysregulated migration and proliferative signaling in multiple disease-relevant models, supporting its use as a node for studying cytoskeletal control and metastatic-like phenotypes.
LASP-1 Double Nickase Plasmid (m) consists of a matched pair of plasmids engineered for high-specificity editing of the Lasp1 locus in mouse cell lines. Each plasmid expresses a Cas9 D10A nickase and a distinct sgRNA targeting opposite DNA strands within Lasp1. 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 Lasp1 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 Lasp1-disrupted clones.
