Mouse Gsn encodes gelsolin, a multifunctional actin-binding protein that severs, caps, and nucleates actin filaments to control cytoskeletal remodeling. By regulating actin dynamics downstream of calcium signaling and phosphoinositide interactions, gelsolin influences cell shape changes, migration, adhesion, endocytosis, and wound-like membrane repair processes. Gelsolin activity intersects with pathways governing mechanotransduction and inflammatory cell behavior, making Gsn expression and regulation relevant to studies of tissue remodeling, neuroinflammation, and tumor-associated motility phenotypes. Altered gelsolin levels have been reported across diverse disease contexts where actin cytoskeleton organization and stress responses are perturbed.
Gelsolin CRISPR Activation Plasmid (m) provides a targeted, non-destructive approach to upregulating endogenous Gsn expression without altering the underlying DNA sequence.
Gelsolin CRISPR Activation Plasmid (m) is a three-plasmid synergistic activation mediator (SAM) system engineered for highly efficient, site-specific transcriptional upregulation of the Gsn 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 Gsn transcriptional start site, where VP64, p65, and HSF1 act in concert to recruit transcriptional machinery and drive upregulation of endogenous Gelsolin expression. Unlike nuclease-active Cas9, dCas9 does not introduce double-strand breaks or modify the genomic sequence, preserving the native Gsn locus and enabling the study of Gelsolin-dependent transcriptional responses at the endogenous locus, making it a valuable tool for functional studies, target gene identification, and the modeling of Gelsolin pathway restoration in tumor cells with silenced or reduced Gsn expression.
