TBC1D20 Lentiviral Activation Particles (m) | sc-426458-LAC | 200 µl | $455.00 |
Mouse Tbc1d20 encodes TBC1D20, a TBC domain–containing Rab GTPase-activating protein that regulates membrane trafficking by accelerating GTP hydrolysis on select Rab proteins. TBC1D20 localizes predominantly to the endoplasmic reticulum and contributes to ER homeostasis, secretory pathway organization, and Golgi-ER transport dynamics that shape lipid handling and organelle morphology. Through these roles, it influences processes such as vesicle tethering/fusion, cargo sorting, and maintenance of intracellular compartment identity. Dysregulation of Rab-dependent trafficking and ER function is relevant to studies of metabolic stress, neurobiology, and cellular proteostasis, making Tbc1d20 a useful node for pathway interrogation in mouse models.
TBC1D20 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 Tbc1d20 upregulation across a broader range of human cell types.
TBC1D20 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 Tbc1d20 transcriptional start site, where VP64, p65, and HSF1 act cooperatively to recruit endogenous transcriptional machinery and drive sustained upregulation of endogenous TBC1D20 expression. The use of nuclease-inactive dCas9 avoids the introduction of double-strand DNA breaks and preserves the native Tbc1d20 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.
