Human GAB2 encodes the scaffolding adaptor protein Gab 2, a docking platform that couples activated receptor tyrosine kinases and cytokine receptors to downstream signaling enzymes. Through phosphorylation-dependent recruitment of SHP2, PI3K (p85), and other effectors, Gab 2 helps propagate PI3K–AKT and RAS–ERK/MAPK pathway signaling that regulates proliferation, survival, migration, and differentiation. Gab 2 also intersects with immune receptor signaling and hematopoietic growth factor responses, influencing cellular activation states and lineage decisions. Dysregulated GAB2 signaling or altered expression has been associated with oncogenic signaling networks and inflammatory phenotypes, making it relevant for mechanistic studies of pathway rewiring and signal integration.
Gab 2 Double Nickase Plasmid (h) consists of a matched pair of plasmids engineered for high-specificity editing of the GAB2 locus in human cell lines. Each plasmid expresses a Cas9 D10A nickase and a distinct sgRNA targeting opposite DNA strands within GAB2. 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 GAB2 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 GAB2-disrupted clones.
