PARL CRISPR Activation Plasmid (h) | sc-403965-ACT | 20 µg | $397.00 |
PARL (presenilin associated rhomboid like) encodes a mitochondrial inner membrane rhomboid serine protease that regulates mitochondrial quality control by processing substrates involved in mitophagy, cristae remodeling, and apoptosis. PARL-dependent proteolysis influences PINK1/Parkin signaling through cleavage of PINK1, thereby modulating mitochondrial depolarization responses and organelle turnover. By shaping OPA1-related mitochondrial dynamics and cytochrome c–linked apoptotic susceptibility, PARL connects bioenergetic homeostasis with stress signaling pathways. Dysregulated PARL activity and altered mitochondrial proteostasis have been implicated in neurodegeneration, metabolic dysfunction, and cancer-relevant mitochondrial reprogramming, supporting its use as a functional node in mitochondrial pathway research.
PARL CRISPR Activation Plasmid (h) provides a targeted, non-destructive approach to upregulating endogenous PARL expression without altering the underlying DNA sequence.
PARL CRISPR Activation Plasmid (h) is a three-plasmid synergistic activation mediator (SAM) system engineered for highly efficient, site-specific transcriptional upregulation of the PARL 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 PARL transcriptional start site, where VP64, p65, and HSF1 act in concert to recruit transcriptional machinery and drive upregulation of endogenous PARL expression. Unlike nuclease-active Cas9, dCas9 does not introduce double-strand breaks or modify the genomic sequence, preserving the native PARL locus and enabling the study of PARL-dependent transcriptional responses at the endogenous locus, making it a valuable tool for functional studies, target gene identification, and the modeling of PARL pathway restoration in tumor cells with silenced or reduced PARL expression.
