Cadps encodes CAPS-1, a Ca2+-dependent activator protein that promotes priming of dense-core vesicles and regulates regulated exocytosis in neuroendocrine and neuronal cells. By coordinating vesicle readiness and coupling Ca2+ signaling to secretion, CAPS-1 supports neurotransmitter and neuropeptide release, hormone secretion, and synaptic function. CAPS-1 activity intersects with SNARE-mediated membrane fusion and presynaptic vesicle cycling processes that shape excitability and network communication. Dysregulation of secretory pathway control is relevant to mechanisms studied in neurodevelopmental and neuropsychiatric phenotypes, as well as endocrine secretion defects, making mouse Cadps a useful model for secretion-linked cellular dysfunction.
CAPS-1 CRISPR Activation Plasmid (m) provides a targeted, non-destructive approach to upregulating endogenous Cadps expression without altering the underlying DNA sequence.
CAPS-1 CRISPR Activation Plasmid (m) is a three-plasmid synergistic activation mediator (SAM) system engineered for highly efficient, site-specific transcriptional upregulation of the Cadps 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 Cadps transcriptional start site, where VP64, p65, and HSF1 act in concert to recruit transcriptional machinery and drive upregulation of endogenous CAPS-1 expression. Unlike nuclease-active Cas9, dCas9 does not introduce double-strand breaks or modify the genomic sequence, preserving the native Cadps locus and enabling the study of CAPS-1-dependent transcriptional responses at the endogenous locus, making it a valuable tool for functional studies, target gene identification, and the modeling of CAPS-1 pathway restoration in tumor cells with silenced or reduced Cadps expression.
