HECTD1 Lentiviral Activation Particles (m) | sc-431500-LAC | 200 µl | $455.00 |
Mouse Hectd1 encodes HECTD1, a HECT-domain E3 ubiquitin ligase that catalyzes ubiquitin transfer to protein substrates to regulate their stability, localization, and signaling output. HECTD1 has been linked to control of cytoskeletal organization and cell polarity, influencing processes such as cell migration, epithelial morphogenesis, and tissue patterning during development. Through ubiquitin-dependent modulation of pathway components, HECTD1 is studied in the context of proteostasis networks and signaling cascades that govern differentiation and stress responses. Dysregulation of E3 ligase activity and ubiquitin signaling is broadly relevant to congenital defects and neurodevelopmental and oncogenic phenotypes, making Hectd1 a useful node for mechanistic research in mouse systems.
HECTD1 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 Hectd1 upregulation across a broader range of human cell types.
HECTD1 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 Hectd1 transcriptional start site, where VP64, p65, and HSF1 act cooperatively to recruit endogenous transcriptional machinery and drive sustained upregulation of endogenous HECTD1 expression. The use of nuclease-inactive dCas9 avoids the introduction of double-strand DNA breaks and preserves the native Hectd1 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.
