TPCN2 Lentiviral Activation Particles (h): sc-402960-LAC
- Target species: human
- 200 µl of transduction-ready, high-titer CRISPR/dCas9 Lentiviral Activation Particles
- TPCN2 Lentiviral Activation Particles (h) is a synergistic activation mediator (SAM) transcription activation system designed to specifically and efficiently upregulate gene expression via lentiviral transduction of cells
- TPCN2 Lentiviral Activation Particles (h) contain the following SAM Activation elements: a deactivated Cas9 (dCas9) nuclease (D10A and N863A) fused to the transactivation domain VP64, an MS2-p65-HSF1 fusion protein and a target-specific 20 nt guide RNA. They also contain the blasticidin, hygromycin and puromycin resistance genes
- Upon transduction, the SAM complex binds to a site-specific region approximately 200-250 nt upstream of the transcriptional start site and provides robust recruitment of transcription factors for highly efficient gene activation
- gRNAs encoded by TPCN2 Lentiviral Activation Plasmid (h) and TPCN2 Lentiviral Activation Plasmid (h2) target distinct regulatory regions of the TPCN2 promoter. One or both designs may be available

TPCN2 (two-pore channel 2) encodes an endolysosomal cation channel that regulates intracellular ion flux, with prominent roles in NAADP-dependent Ca²⁺ signaling from acidic organelles. By shaping endosome–lysosome dynamics, vesicular trafficking, and organelle excitability, TPCN2 influences downstream processes including autophagy, membrane fusion events, and Ca²⁺-dependent signaling cascades. Variation in TPCN2 activity has been linked to altered pigmentation biology and to metabolic phenotypes, and dysregulated endolysosomal signaling involving TPCN2 is relevant to studies of neurodegeneration and cancer cell behavior. These features make TPCN2 a useful target for dissecting lysosomal signaling networks and Ca²⁺-regulated cellular responses in human model systems.
TPCN2 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 TPCN2 upregulation across a broader range of human cell types.
TPCN2 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 TPCN2 transcriptional start site, where VP64, p65, and HSF1 act cooperatively to recruit endogenous transcriptional machinery and drive sustained upregulation of endogenous TPCN2 expression. The use of nuclease-inactive dCas9 avoids the introduction of double-strand DNA breaks and preserves the native TPCN2 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.
