KIBRA CRISPR Activation Plasmid (h) | sc-402677-ACT | 20 µg | $397.00 |
WWC1 encodes KIBRA, a scaffold protein enriched in brain and kidney that coordinates signaling at the cell cortex and synapses through WW domains and PDZ-binding interactions. KIBRA participates in Hippo pathway regulation by modulating LATS1/2 activity and YAP/TAZ transcriptional programs, linking cell polarity, proliferation, and mechanotransduction to transcriptional control. It also interfaces with trafficking and actin-cytoskeleton regulators to influence membrane dynamics and synaptic plasticity, with reported roles in learning and memory-associated pathways. Altered WWC1/KIBRA expression or signaling has been associated with neurocognitive phenotypes and dysregulated growth control relevant to oncology and other complex disease models.
KIBRA CRISPR Activation Plasmid (h) provides a targeted, non-destructive approach to upregulating endogenous WWC1 expression without altering the underlying DNA sequence.
KIBRA CRISPR Activation Plasmid (h) is a three-plasmid synergistic activation mediator (SAM) system engineered for highly efficient, site-specific transcriptional upregulation of the WWC1 locus in human cell lines. The system is built around a catalytically inactive Cas9 (dCas9) carrying two inactivating mutations (D10A and N863A) that eliminate nuclease activity while preserving DNA binding. This dCas9 is fused to VP64, a potent transcriptional activator, and is co-expressed with a blasticidin resistance gene for selection. The second plasmid encodes the MS2-p65-HSF1 fusion protein, a secondary activator complex that works in concert with dCas9-VP64, alongside a hygromycin resistance gene. The third plasmid encodes a target-specific 20 nt sgRNA fused to two MS2 RNA aptamers that recruit the MS2-p65-HSF1 complex to the activation site, accompanied by a puromycin resistance gene. The three plasmids are delivered at a 1:1:1 mass ratio for balanced expression of all system components.
Once assembled at the target locus, the SAM complex binds within approximately 200 bp upstream of the WWC1 transcriptional start site, where VP64, p65, and HSF1 act in concert to recruit transcriptional machinery and drive upregulation of endogenous KIBRA expression. Unlike nuclease-active Cas9, dCas9 does not introduce double-strand breaks or modify the genomic sequence, preserving the native WWC1 locus and enabling the study of KIBRA-dependent transcriptional responses at the endogenous locus, making it a valuable tool for functional studies, target gene identification, and the modeling of KIBRA pathway restoration in tumor cells with silenced or reduced WWC1 expression.
