KIBRA Lentiviral Activation Particles (h) | sc-402677-LAC | 200 µl | $455.00 |
WWC1 encodes KIBRA, a scaffolding protein enriched in brain and kidney that integrates Hippo pathway signaling with cytoskeletal organization, cell polarity, and membrane trafficking. KIBRA interacts with core Hippo components and polarity regulators to modulate YAP/TAZ-dependent transcriptional programs that influence proliferation, differentiation, and tissue homeostasis. It also contributes to synaptic function and memory-related signaling through coordination of receptor trafficking and actin dynamics. Altered WWC1/KIBRA regulation has been linked to neurocognitive phenotypes and dysregulated growth control in disease-relevant cellular contexts, making it a useful node for pathway-focused mechanistic studies.
KIBRA 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 WWC1 upregulation across a broader range of human cell types.
KIBRA 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 WWC1 transcriptional start site, where VP64, p65, and HSF1 act cooperatively to recruit endogenous transcriptional machinery and drive sustained upregulation of endogenous KIBRA expression. The use of nuclease-inactive dCas9 avoids the introduction of double-strand DNA breaks and preserves the native WWC1 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.
