nephrin Lentiviral Activation Particles (h) | sc-400368-LAC | 200 µl | $455.00 |
Human NPHS1 encodes nephrin, a transmembrane immunoglobulin superfamily protein that is a core structural component of the slit diaphragm between podocyte foot processes. Nephrin organizes the filtration barrier by forming extracellular zipper-like interactions and coordinating intracellular signaling via adaptor proteins such as NCK, linking slit diaphragm integrity to actin cytoskeletal remodeling. NPHS1-dependent pathways contribute to podocyte polarity, cell–cell junction dynamics, and mechanosensitive responses that maintain glomerular permselectivity. Disruption or dysregulation of nephrin is strongly associated with podocyte injury phenotypes and proteinuric kidney disease mechanisms, making NPHS1 a key target for studying glomerular barrier biology.
nephrin 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 NPHS1 upregulation across a broader range of human cell types.
nephrin 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 NPHS1 transcriptional start site, where VP64, p65, and HSF1 act cooperatively to recruit endogenous transcriptional machinery and drive sustained upregulation of endogenous nephrin expression. The use of nuclease-inactive dCas9 avoids the introduction of double-strand DNA breaks and preserves the native NPHS1 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.
