TIMP3 encodes tissue inhibitor of metalloproteinases-3 (TIMP-3), an extracellular matrix–bound inhibitor of multiple MMPs and ADAM/ADAMTS proteases that constrains pericellular proteolysis and stabilizes matrix architecture. By modulating shedding of surface receptors and ligands, TIMP-3 influences EGFR and TNF signaling, cell migration, angiogenesis, and inflammatory responses within tissue microenvironments. Its activity is closely linked to extracellular matrix remodeling programs that shape fibrosis, vascular homeostasis, and tumor–stroma interactions. Altered TIMP3 expression or function has been associated with dysregulated matrix turnover and pathologies such as cardiovascular remodeling, chronic inflammation, and cancer progression.
TIMP-3 Double Nickase Plasmid (h) consists of a matched pair of plasmids engineered for high-specificity editing of the TIMP3 locus in human cell lines. Each plasmid expresses a Cas9 D10A nickase and a distinct sgRNA targeting opposite DNA strands within TIMP3. 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 TIMP3 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 TIMP3-disrupted clones.
