INPP5E Lentiviral Activation Particles (h) | sc-405923-LAC | 200 µl | $455.00 |
INPP5E encodes inositol polyphosphate-5-phosphatase E, a phosphoinositide 5-phosphatase that hydrolyzes PI(4,5)P2 and PI(3,4,5)P3 to shape membrane phosphoinositide composition. INPP5E is enriched at the primary cilium and contributes to ciliary membrane identity, trafficking, and signaling, including modulation of Hedgehog pathway output and broader PI3K–AKT-linked lipid signaling dynamics. By controlling phosphoinositide gradients, INPP5E helps coordinate ciliogenesis, receptor localization, and downstream second-messenger responses. Disruption of INPP5E function is associated with ciliopathy phenotypes and neurodevelopmental disorders, making it a relevant target for mechanistic studies of cilia-dependent signaling and membrane lipid regulation.
INPP5E 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 INPP5E upregulation across a broader range of human cell types.
INPP5E 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 INPP5E transcriptional start site, where VP64, p65, and HSF1 act cooperatively to recruit endogenous transcriptional machinery and drive sustained upregulation of endogenous INPP5E expression. The use of nuclease-inactive dCas9 avoids the introduction of double-strand DNA breaks and preserves the native INPP5E 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.
