p115 Lentiviral Activation Particles (h) | sc-403918-LAC | 200 µl | $455.00 |
USO1 encodes p115, a peripheral membrane coiled-coil tethering factor that coordinates vesicle docking and fusion in the early secretory pathway. p115 bridges COPII-derived carriers and Golgi membranes by interacting with Rab GTPases and golgins, supporting ER-to-Golgi trafficking, Golgi ribbon organization, and mitotic Golgi reassembly. Through its role in membrane trafficking and organelle architecture, p115 influences proteostasis, receptor and integrin surface delivery, and signaling outputs linked to proliferation and migration. Dysregulated secretory transport and Golgi stress pathways involving p115 have been investigated in contexts such as neurodegeneration, infection, and cancer-associated changes in glycosylation and secretion.
p115 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 USO1 upregulation across a broader range of human cell types.
p115 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 USO1 transcriptional start site, where VP64, p65, and HSF1 act cooperatively to recruit endogenous transcriptional machinery and drive sustained upregulation of endogenous p115 expression. The use of nuclease-inactive dCas9 avoids the introduction of double-strand DNA breaks and preserves the native USO1 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.
