C1QBP Lentiviral Activation Particles (h) | sc-400911-LAC | 200 µl | $455.00 |
C1QBP (complement component 1q binding protein; p32/gC1qR) is a multifunctional, predominantly mitochondrial protein that also localizes to other cellular compartments and interfaces with innate immune and stress-response signaling. It supports mitochondrial oxidative phosphorylation, mitoribosome-related processes, and cellular energy homeostasis, linking metabolic state to proliferation and survival programs. C1QBP has been connected to complement/kinin system interactions and modulation of inflammatory signaling, positioning it at the intersection of immunity and metabolism. Altered C1QBP expression or localization has been reported across cancer and inflammatory disease contexts, making it relevant for studying tumor bioenergetics, immune microenvironment crosstalk, and mitochondrial dysfunction.
C1QBP 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 C1QBP upregulation across a broader range of human cell types.
C1QBP 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 C1QBP transcriptional start site, where VP64, p65, and HSF1 act cooperatively to recruit endogenous transcriptional machinery and drive sustained upregulation of endogenous C1QBP expression. The use of nuclease-inactive dCas9 avoids the introduction of double-strand DNA breaks and preserves the native C1QBP 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.
