P/Q-type Ca++ CP α1A CRISPR Activation Plasmid (h): sc-404267-ACT
- Target species: human
- 20 µg of transfection-ready, purified plasmid DNA; Suitable for up to 20 transfections
- P/Q-type Ca++ CP α1A CRISPR Activation Plasmid (h) is a synergistic activation mediator (SAM) transcription activation system designed to specifically upregulate gene expression
- P/Q-type Ca++ CP α1A CRISPR Activation Plasmid (h) consists of three plasmids at a 1:1:1 mass ratio: a plasmid encoding the deactivated Cas9 (dCas9) nuclease (D10A and N863A) fused to the transactivation domain VP64, and a blasticidin resistance gene; a plasmid encoding the MS2-p65-HSF1 fusion protein, and a hygromycin resistance gene; a plasmid encoding a target-specific 20 nt guide RNA fused to two MS2 RNA aptamers, and a puromycin resistance gene
- The resulting SAM complex binds to a site-specific region approximately 200-250 nt upstream of the transcriptional start site and provides robust recruitment of transcription factors for highly efficient gene activation
- gRNAs encoded by P/Q-type Ca++ CP α1A CRISPR Activation Plasmid (h) and P/Q-type Ca++ CP α1A CRISPR Activation Plasmid (h2) target distinct regulatory regions upstream of the CACNA1A transcriptional start site. One or both designs may be available
- Following transfection, gene knockout efficiency can be assayed by WB, IF or IHC using antibody: P/Q-type Ca++ CP α1A Antibody (C-2): sc-390004

CACNA1A encodes the α1A pore-forming subunit of P/Q-type voltage-gated calcium channels (CaV2.1) that mediate high-voltage–activated Ca²⁺ influx in excitable cells. In neurons, CaV2.1 is enriched at presynaptic active zones where it couples membrane depolarization to Ca²⁺-dependent synaptic vesicle fusion, shaping neurotransmitter release probability, short-term plasticity, and network excitability. Channel activity integrates with Ca²⁺-regulated signaling pathways, including calmodulin-dependent modulation, phosphorylation by PKA/PKC, and downstream transcriptional programs responsive to intracellular Ca²⁺ dynamics. Genetic variation or dysregulation of CACNA1A is linked to neurological phenotypes involving cerebellar and cortical circuits, supporting its use in studies of synaptic physiology and neurodevelopmental mechanisms.
P/Q-type Ca++ CP α1A CRISPR Activation Plasmid (h) provides a targeted, non-destructive approach to upregulating endogenous CACNA1A expression without altering the underlying DNA sequence.
P/Q-type Ca++ CP α1A CRISPR Activation Plasmid (h) is a three-plasmid synergistic activation mediator (SAM) system engineered for highly efficient, site-specific transcriptional upregulation of the CACNA1A 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 CACNA1A transcriptional start site, where VP64, p65, and HSF1 act in concert to recruit transcriptional machinery and drive upregulation of endogenous P/Q-type Ca++ CP α1A expression. Unlike nuclease-active Cas9, dCas9 does not introduce double-strand breaks or modify the genomic sequence, preserving the native CACNA1A locus and enabling the study of P/Q-type Ca++ CP α1A-dependent transcriptional responses at the endogenous locus, making it a valuable tool for functional studies, target gene identification, and the modeling of P/Q-type Ca++ CP α1A pathway restoration in tumor cells with silenced or reduced CACNA1A expression.
