Human SRC encodes Src, a non-receptor tyrosine kinase that integrates signals from receptor tyrosine kinases, integrins, and immune receptors to regulate proliferation, survival, adhesion, and cytoskeletal remodeling. Src activity propagates through pathways such as RAS–MAPK, PI3K–AKT, and focal adhesion signaling, shaping cell migration and mechanotransduction. Dysregulated SRC signaling is frequently associated with oncogenic phenotypes including enhanced invasion, epithelial–mesenchymal transition programs, and altered interactions with the tumor microenvironment. SRC is also used as a model kinase for studying phosphorylation-dependent signaling networks and feedback control in diverse human cell types.
Src Double Nickase Plasmid (h) consists of a matched pair of plasmids engineered for high-specificity editing of the SRC locus in human cell lines. Each plasmid expresses a Cas9 D10A nickase and a distinct sgRNA targeting opposite DNA strands within SRC. 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 SRC 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 SRC-disrupted clones.
