CELSR1 CRISPR Activation Plasmid (h) | sc-405564-ACT | 20 µg | $397.00 |
CELSR1 (cadherin EGF LAG seven-pass G-type receptor 1) encodes an atypical adhesion GPCR that functions as a core component of the planar cell polarity (PCP) machinery. Through extracellular cadherin repeats and intracellular signaling interfaces, CELSR1 coordinates directional cell behaviors, epithelial organization, and polarized cytoskeletal dynamics during development and tissue remodeling. It intersects functionally with non-canonical WNT/PCP signaling and cooperates with proteins such as VANGL and FZD to regulate oriented cell division and collective migration. Dysregulated CELSR1 activity or expression has been linked to developmental defects and aberrant tissue patterning, and altered PCP signaling is frequently studied in contexts of invasion, morphogenesis, and barrier integrity.
CELSR1 CRISPR Activation Plasmid (h) provides a targeted, non-destructive approach to upregulating endogenous CELSR1 expression without altering the underlying DNA sequence.
CELSR1 CRISPR Activation Plasmid (h) is a three-plasmid synergistic activation mediator (SAM) system engineered for highly efficient, site-specific transcriptional upregulation of the CELSR1 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 CELSR1 transcriptional start site, where VP64, p65, and HSF1 act in concert to recruit transcriptional machinery and drive upregulation of endogenous CELSR1 expression. Unlike nuclease-active Cas9, dCas9 does not introduce double-strand breaks or modify the genomic sequence, preserving the native CELSR1 locus and enabling the study of CELSR1-dependent transcriptional responses at the endogenous locus, making it a valuable tool for functional studies, target gene identification, and the modeling of CELSR1 pathway restoration in tumor cells with silenced or reduced CELSR1 expression.
