Radixin Lentiviral Activation Particles (m) | sc-422634-LAC | 200 µl | $455.00 |
Mouse Rdx encodes radixin, an ERM (ezrin–radixin–moesin) family scaffold that links cortical F-actin to the plasma membrane and organizes specialized membrane domains. Radixin regulates cell shape, adhesion, and migration by coordinating actin remodeling with membrane protein positioning, influencing processes such as microvilli formation and junctional integrity. Through interactions with Rho-family signaling and phosphoinositide-dependent activation, radixin contributes to cytoskeletal dynamics and mechanotransduction. Altered ERM network function has been associated with epithelial disorganization, invasive behavior, and other cytoskeleton-related phenotypes relevant to cancer biology and tissue homeostasis studies.
Radixin Lentiviral Activation Particles (m) address this need by packaging the complete synergistic activation mediator (SAM) transcriptional activation system into transduction-ready, high-titer lentiviral particles, enabling efficient Rdx upregulation across a broader range of human cell types.
Radixin Lentiviral Activation Particles (m) deliver all functional components of the synergistic activation mediator (SAM) system via lentiviral transduction. The system comprises three particle preparations co-transduced into target cells: one encoding catalytically inactive dCas9 (D10A and N863A mutations) fused to the VP64 transactivation domain with a blasticidin resistance gene; one encoding the MS2-p65-HSF1 fusion protein with a hygromycin resistance gene; and one encoding a target-specific 20 nt sgRNA fused to two MS2 RNA aptamers with a puromycin resistance gene. Following lentiviral transduction and genomic integration of the expression cassettes, the SAM components are stably expressed and assemble at the target locus within the proximal promoter region upstream of the Rdx transcriptional start site, where VP64, p65, and HSF1 act cooperatively to recruit endogenous transcriptional machinery and drive sustained upregulation of endogenous Radixin expression. The use of nuclease-inactive dCas9 avoids the introduction of double-strand DNA breaks and preserves the native Rdx genomic locus and regulatory architecture.
The lentiviral format offers several practical advantages: stable genomic integration supports heritable activation across cell divisions; high-titer particle preparations eliminate the need for in-house viral production; and compatibility with primary, non-dividing, and transfection-resistant cell types expands experimental accessibility. Successful transduction can be confirmed and enriched through triple antibiotic selection using puromycin, hygromycin, and blasticidin.
