OPA1 CRISPR Activation Plasmid (h) | sc-401555-ACT | 20 µg | $397.00 |
Human OPA1 encodes a dynamin-like GTPase embedded in the inner mitochondrial membrane that governs mitochondrial fusion, cristae architecture, and maintenance of respiratory chain supercomplex organization. Through coordination with mitochondrial dynamics factors such as MFN1/2 and DRP1, OPA1 supports oxidative phosphorylation efficiency, mitochondrial DNA stability, and bioenergetic adaptation to cellular stress. OPA1 function intersects with apoptotic signaling by regulating cristae remodeling and cytochrome c mobilization, linking mitochondrial structure to intrinsic cell death pathways. Pathogenic OPA1 dysregulation is associated with mitochondrial network fragmentation and neurodegeneration phenotypes, including autosomal dominant optic atrophy, making it relevant for studies of neuronal resilience and metabolic dysfunction.
OPA1 CRISPR Activation Plasmid (h) provides a targeted, non-destructive approach to upregulating endogenous OPA1 expression without altering the underlying DNA sequence.
OPA1 CRISPR Activation Plasmid (h) is a three-plasmid synergistic activation mediator (SAM) system engineered for highly efficient, site-specific transcriptional upregulation of the OPA1 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 OPA1 transcriptional start site, where VP64, p65, and HSF1 act in concert to recruit transcriptional machinery and drive upregulation of endogenous OPA1 expression. Unlike nuclease-active Cas9, dCas9 does not introduce double-strand breaks or modify the genomic sequence, preserving the native OPA1 locus and enabling the study of OPA1-dependent transcriptional responses at the endogenous locus, making it a valuable tool for functional studies, target gene identification, and the modeling of OPA1 pathway restoration in tumor cells with silenced or reduced OPA1 expression.
