Polycystin-1 Lentiviral Activation Particles (h) | sc-400983-LAC | 200 µl | $455.00 |
PKD1 encodes polycystin-1, a large membrane-associated receptor-like protein that forms a mechanosensory complex with polycystin-2 to regulate calcium signaling in primary cilia and at cell–cell junctions. Polycystin-1 influences epithelial polarity, tubular morphogenesis, and extracellular matrix interactions, integrating cues that converge on pathways such as Ca2+-dependent signaling, cAMP modulation, and cytoskeletal remodeling. Disruption of PKD1 function is strongly linked to autosomal dominant polycystic kidney disease, where altered mechanotransduction and epithelial organization contribute to cyst initiation and expansion. In broader systems, PKD1 activity is studied in contexts of tissue architecture, ciliopathy-associated signaling, and cellular responses to mechanical stress.
Polycystin-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 PKD1 upregulation across a broader range of human cell types.
Polycystin-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 PKD1 transcriptional start site, where VP64, p65, and HSF1 act cooperatively to recruit endogenous transcriptional machinery and drive sustained upregulation of endogenous Polycystin-1 expression. The use of nuclease-inactive dCas9 avoids the introduction of double-strand DNA breaks and preserves the native PKD1 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.
