LTBP1 encodes latent transforming growth factor beta binding protein 1 (LTBP-1), an extracellular matrix glycoprotein that sequesters and regulates latent TGF-β complexes, coordinating their deposition, storage, and activation in connective tissues. By controlling spatial and temporal TGF-β bioavailability, LTBP-1 influences SMAD-dependent signaling, matrix remodeling, cell adhesion, and mechanotransduction during development and tissue homeostasis. Dysregulated LTBP1 expression or altered microfibril-associated localization can perturb TGF-β pathway tone and extracellular matrix organization, linking this axis to fibrotic remodeling, vascular and cardiac structural phenotypes, and tumor microenvironment biology. LTBP-1 is therefore widely studied in pathways governing epithelial–mesenchymal plasticity, inflammation-associated remodeling, and stromal–parenchymal signaling crosstalk.
LTBP-1 Double Nickase Plasmid (h) consists of a matched pair of plasmids engineered for high-specificity editing of the LTBP1 locus in human cell lines. Each plasmid expresses a Cas9 D10A nickase and a distinct sgRNA targeting opposite DNA strands within LTBP1. 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 LTBP1 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 LTBP1-disrupted clones.
