Kremen-1 CRISPR Activation Plasmid (h) | sc-403791-ACT | 20 µg | $397.00 |
Human KREMEN1 encodes Kremen-1, a single-pass transmembrane receptor that serves as a high-affinity binding partner for Dickkopf (DKK) proteins and cooperates with LRP5/6 to modulate canonical Wnt/β-catenin signaling. By promoting DKK-dependent internalization of LRP6, Kremen-1 influences cell fate decisions, proliferation, and differentiation programs, with downstream effects on tissue patterning and epithelial–mesenchymal dynamics. KREMEN1 activity intersects with receptor trafficking and endocytosis processes that shape signal amplitude and duration at the cell surface. Dysregulated Wnt pathway modulation involving Kremen-1 has been associated with developmental phenotypes and cancer-related signaling contexts where Wnt responsiveness and receptor availability are altered.
Kremen-1 CRISPR Activation Plasmid (h) provides a targeted, non-destructive approach to upregulating endogenous KREMEN1 expression without altering the underlying DNA sequence.
Kremen-1 CRISPR Activation Plasmid (h) is a three-plasmid synergistic activation mediator (SAM) system engineered for highly efficient, site-specific transcriptional upregulation of the KREMEN1 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 KREMEN1 transcriptional start site, where VP64, p65, and HSF1 act in concert to recruit transcriptional machinery and drive upregulation of endogenous Kremen-1 expression. Unlike nuclease-active Cas9, dCas9 does not introduce double-strand breaks or modify the genomic sequence, preserving the native KREMEN1 locus and enabling the study of Kremen-1-dependent transcriptional responses at the endogenous locus, making it a valuable tool for functional studies, target gene identification, and the modeling of Kremen-1 pathway restoration in tumor cells with silenced or reduced KREMEN1 expression.
