Cdt2 Lentiviral Activation Particles (h) | sc-407212-LAC | 200 µl | $455.00 |
Human DTL encodes Cdt2, a substrate receptor for the CRL4^Cdt2 E3 ubiquitin ligase that coordinates ubiquitin-dependent proteolysis during S phase and after DNA damage. By coupling PCNA loading on chromatin to targeted degradation of key replication and checkpoint proteins such as CDT1, p21 (CDKN1A), and SETD8, Cdt2 enforces replication licensing control and genome stability. This PCNA-dependent pathway integrates with ATR/Chk1 signaling, S-phase checkpoint control, and DNA repair to prevent rereplication and replication stress. Dysregulated DTL/Cdt2 activity is frequently associated with proliferative phenotypes and genomic instability signatures observed in multiple cancers, making it relevant for studies of cell cycle control and tumor biology.
Cdt2 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 DTL upregulation across a broader range of human cell types.
Cdt2 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 DTL transcriptional start site, where VP64, p65, and HSF1 act cooperatively to recruit endogenous transcriptional machinery and drive sustained upregulation of endogenous Cdt2 expression. The use of nuclease-inactive dCas9 avoids the introduction of double-strand DNA breaks and preserves the native DTL 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.
