LASP-1 Lentiviral Activation Particles (h) | sc-404630-LAC | 200 µl | $455.00 |
LASP1 encodes LIM and SH3 domain protein 1 (LASP-1), an actin-binding focal adhesion adaptor that localizes to lamellipodia, stress fibers, and cell–cell junctions to coordinate cytoskeletal remodeling. LASP-1 couples signaling at adhesion complexes with actin dynamics, influencing processes such as cell migration, membrane protrusion formation, and mechanotransduction. Through interactions with proteins including zyxin, VASP, and components of focal adhesion signaling, LASP-1 is linked to pathways governing adhesion turnover and motility. Dysregulated LASP1 expression has been reported across multiple tumor contexts and is frequently investigated for roles in invasion, metastasis-associated phenotypes, and cytoskeleton-dependent transcriptional programs.
LASP-1 Lentiviral Activation Particles (h) address this need by packaging the complete synergistic activation mediator (SAM) transcriptional activation system into transduction-ready, high-titer lentiviral particles, enabling efficient LASP1 upregulation across a broader range of human cell types.
LASP-1 Lentiviral Activation Particles (h) 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 LASP1 transcriptional start site, where VP64, p65, and HSF1 act cooperatively to recruit endogenous transcriptional machinery and drive sustained upregulation of endogenous LASP-1 expression. The use of nuclease-inactive dCas9 avoids the introduction of double-strand DNA breaks and preserves the native LASP1 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.
