PKD2 encodes polycystin-2, a Ca2+-permeable nonselective cation channel that localizes to primary cilia, endoplasmic reticulum, and plasma membrane where it helps regulate mechanosensory calcium signaling. Polycystin-2 interacts with polycystin-1 and contributes to control of intracellular Ca2+ homeostasis, cellular polarity, and epithelial tubule morphogenesis, integrating cues that influence proliferation and differentiation programs. PKD2-dependent signaling intersects with cAMP and MAPK-associated responses and modulates fluid flow–dependent signaling in renal epithelia. Genetic disruption or dysregulation of PKD2 is strongly associated with autosomal dominant polycystic kidney disease and related cystic phenotypes, making it a key target for studying ciliopathy mechanisms.
Polycystin-2 CRISPR Activation Plasmid (h) provides a targeted, non-destructive approach to upregulating endogenous PKD2 expression without altering the underlying DNA sequence.
Polycystin-2 CRISPR Activation Plasmid (h) is a three-plasmid synergistic activation mediator (SAM) system engineered for highly efficient, site-specific transcriptional upregulation of the PKD2 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 PKD2 transcriptional start site, where VP64, p65, and HSF1 act in concert to recruit transcriptional machinery and drive upregulation of endogenous Polycystin-2 expression. Unlike nuclease-active Cas9, dCas9 does not introduce double-strand breaks or modify the genomic sequence, preserving the native PKD2 locus and enabling the study of Polycystin-2-dependent transcriptional responses at the endogenous locus, making it a valuable tool for functional studies, target gene identification, and the modeling of Polycystin-2 pathway restoration in tumor cells with silenced or reduced PKD2 expression.
