GARNL4 Double Nickase Plasmid (h) | sc-411668-NIC | 20 µg | $410.00 |
RAP1GAP2 encodes GARNL4, a Rap GTPase-activating protein that accelerates GTP hydrolysis on Rap1/Rap2 to constrain small GTPase signaling at the plasma membrane and cytoskeleton. By modulating Rap-dependent control of integrin activation, cell adhesion, and actin remodeling, GARNL4 contributes to regulation of platelet and leukocyte signaling, trafficking, and stimulus-coupled responses. This RAP1 pathway intersects with MAPK/ERK and PI3K-linked networks through upstream receptors and adaptor complexes, shaping cellular activation thresholds and secretion dynamics. Dysregulated Rap signaling and altered GAP activity are frequently studied in contexts of abnormal hemostasis, inflammatory signaling, and cancer-associated changes in adhesion and migration.
GARNL4 Double Nickase Plasmid (h) consists of a matched pair of plasmids engineered for high-specificity editing of the RAP1GAP2 locus in human cell lines. Each plasmid expresses a Cas9 D10A nickase and a distinct sgRNA targeting opposite DNA strands within RAP1GAP2. 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 RAP1GAP2 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 RAP1GAP2-disrupted clones.
