Sp1 Lentiviral Activation Particles (m) | sc-423094-LAC | 200 µl | $455.00 |
Mouse Sp1 (specificity protein 1) is a ubiquitously expressed, GC-box–binding transcription factor that coordinates basal and inducible transcription programs controlling cell cycle progression, DNA damage responses, apoptosis, and differentiation. Through interactions with coactivators and chromatin regulators, Sp1 modulates gene networks linked to MAPK and PI3K/AKT signaling, oxidative stress responses, and inflammatory transcriptional outputs. Altered Sp1 activity has been associated with dysregulated proliferation, metabolic rewiring, and aberrant extracellular matrix and cytokine gene expression, making it relevant to studies of cancer biology, neurodegeneration, and immune-mediated pathology. In mouse model systems, Sp1 serves as a central node for investigating transcriptional control of housekeeping and stimulus-responsive genes across diverse tissues.
Sp1 Lentiviral Activation Particles (m) address this need by packaging the complete synergistic activation mediator (SAM) transcriptional activation system into transduction-ready, high-titer lentiviral particles, enabling efficient Sp1 upregulation across a broader range of human cell types.
Sp1 Lentiviral Activation Particles (m) 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 Sp1 transcriptional start site, where VP64, p65, and HSF1 act cooperatively to recruit endogenous transcriptional machinery and drive sustained upregulation of endogenous Sp1 expression. The use of nuclease-inactive dCas9 avoids the introduction of double-strand DNA breaks and preserves the native Sp1 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.
