RAC1 encodes the small Rho family GTPase Rac1, a central regulator of actin cytoskeleton dynamics that controls lamellipodia formation, cell polarity, adhesion turnover, and directed migration. Rac1 signals through effectors such as PAK kinases and the WAVE/Arp2/3 complex, integrating cues from receptor tyrosine kinases and integrins to modulate MAPK signaling, reactive oxygen species generation, and endocytic trafficking. Through these pathways, RAC1 influences proliferation, survival, and barrier function across many cell types. Dysregulated RAC1 activity is frequently studied in the context of oncogenic signaling, metastasis-associated cell motility, inflammatory responses, and neurodevelopmental phenotypes where cytoskeletal remodeling and synaptic plasticity are altered.
Rac 1 CRISPR Activation Plasmid (h) provides a targeted, non-destructive approach to upregulating endogenous RAC1 expression without altering the underlying DNA sequence.
Rac 1 CRISPR Activation Plasmid (h) is a three-plasmid synergistic activation mediator (SAM) system engineered for highly efficient, site-specific transcriptional upregulation of the RAC1 locus in human cell lines. The system is built around a catalytically inactive Cas9 (dCas9) carrying two inactivating mutations (D10A and N863A) that eliminate nuclease activity while preserving DNA binding. This dCas9 is fused to VP64, a potent transcriptional activator, and is co-expressed with a blasticidin resistance gene for selection. The second plasmid encodes the MS2-p65-HSF1 fusion protein, a secondary activator complex that works in concert with dCas9-VP64, alongside a hygromycin resistance gene. The third plasmid encodes a target-specific 20 nt sgRNA fused to two MS2 RNA aptamers that recruit the MS2-p65-HSF1 complex to the activation site, accompanied by a puromycin resistance gene. The three plasmids are delivered at a 1:1:1 mass ratio for balanced expression of all system components.
Once assembled at the target locus, the SAM complex binds within approximately 200 bp upstream of the RAC1 transcriptional start site, where VP64, p65, and HSF1 act in concert to recruit transcriptional machinery and drive upregulation of endogenous Rac 1 expression. Unlike nuclease-active Cas9, dCas9 does not introduce double-strand breaks or modify the genomic sequence, preserving the native RAC1 locus and enabling the study of Rac 1-dependent transcriptional responses at the endogenous locus, making it a valuable tool for functional studies, target gene identification, and the modeling of Rac 1 pathway restoration in tumor cells with silenced or reduced RAC1 expression.
