RAC1 encodes Rac1, a Rho family small GTPase that cycles between active GTP-bound and inactive GDP-bound states to coordinate actin cytoskeleton remodeling, membrane ruffling, and cell polarity. Rac1 signals through effectors such as PAK kinases, WAVE regulatory complex, and NADPH oxidase, integrating cues from receptor tyrosine kinases and integrins to regulate migration, adhesion, endocytosis, and reactive oxygen species generation. In human biology, dysregulated RAC1 activity is linked to altered epithelial–mesenchymal dynamics, invasion programs, and immune cell trafficking, and has been associated with cancer progression, neurodevelopmental disorders, and inflammatory phenotypes. These pathway connections make RAC1 a widely used node for interrogating cytoskeletal control, MAPK crosstalk, and cell-state transitions in mechanistic studies.
Rac 1 Double Nickase Plasmid (h) consists of a matched pair of plasmids engineered for high-specificity editing of the RAC1 locus in human cell lines. Each plasmid expresses a Cas9 D10A nickase and a distinct sgRNA targeting opposite DNA strands within RAC1. 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 RAC1 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 RAC1-disrupted clones.
