DBC-1 Lentiviral Activation Particles (h) | sc-403056-LAC | 200 µl | $455.00 |
CCAR2 encodes DBC-1, a predominantly nuclear regulator that integrates transcriptional control with DNA damage signaling and chromatin-associated processes. DBC-1 modulates the activity of key nuclear enzymes and transcriptional programs, including NAD⁺-dependent deacetylation pathways and stress-responsive gene expression, thereby influencing cell-cycle progression, apoptosis, and genome stability. Through its roles in transcriptional co-regulation and repair-associated signaling, altered CCAR2/DBC-1 function has been linked to dysregulated proliferation and oncogenic phenotypes in multiple tumor contexts. These properties make CCAR2 a useful node for studying epigenetic regulation, checkpoint control, and context-dependent transcriptional networks in human cells.
DBC-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 CCAR2 upregulation across a broader range of human cell types.
DBC-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 CCAR2 transcriptional start site, where VP64, p65, and HSF1 act cooperatively to recruit endogenous transcriptional machinery and drive sustained upregulation of endogenous DBC-1 expression. The use of nuclease-inactive dCas9 avoids the introduction of double-strand DNA breaks and preserves the native CCAR2 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.
