V-ATPase A1 CRISPR Activation Plasmid (h) | sc-400975-ACT | 20 µg | $397.00 |
ATP6V0A1 encodes the a1 isoform of the V0 sector a subunit within vacuolar H+-ATPase (V-ATPase), a multi-subunit proton pump that acidifies endosomes, lysosomes, and secretory vesicles. By supporting organelle acidification, V-ATPase A1 regulates receptor-mediated endocytosis, autophagic flux, lysosomal proteolysis, vesicular trafficking, and nutrient-sensing pathways linked to mTOR signaling. Proper V-ATPase activity is required for pH-dependent protein sorting and membrane fusion events that shape synaptic vesicle cycling and general proteostasis. Dysregulated vesicle and lysosome acidification associated with ATP6V0A1 perturbation is relevant to studies of neurodegeneration, developmental phenotypes, and cellular stress responses driven by impaired degradative capacity.
V-ATPase A1 CRISPR Activation Plasmid (h) provides a targeted, non-destructive approach to upregulating endogenous ATP6V0A1 expression without altering the underlying DNA sequence.
V-ATPase A1 CRISPR Activation Plasmid (h) is a three-plasmid synergistic activation mediator (SAM) system engineered for highly efficient, site-specific transcriptional upregulation of the ATP6V0A1 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 ATP6V0A1 transcriptional start site, where VP64, p65, and HSF1 act in concert to recruit transcriptional machinery and drive upregulation of endogenous V-ATPase A1 expression. Unlike nuclease-active Cas9, dCas9 does not introduce double-strand breaks or modify the genomic sequence, preserving the native ATP6V0A1 locus and enabling the study of V-ATPase A1-dependent transcriptional responses at the endogenous locus, making it a valuable tool for functional studies, target gene identification, and the modeling of V-ATPase A1 pathway restoration in tumor cells with silenced or reduced ATP6V0A1 expression.
