BECN1 encodes Beclin-1, a core scaffold of the class III phosphatidylinositol 3-kinase (PI3KC3/VPS34) complexes that initiate autophagosome nucleation and regulate endosomal trafficking. Through interactions with ATG14, UVRAG, and BCL2-family proteins, Beclin-1 integrates nutrient sensing and stress signals to control autophagic flux, organelle quality control, and innate immune responses. Altered BECN1 activity has been linked to dysregulated proteostasis and inflammation in cancer biology, neurodegeneration, and infectious disease models. As a nodal autophagy regulator, Beclin-1 is widely used to interrogate crosstalk between autophagy, apoptosis, and vesicle-mediated signaling pathways.
BECN1/Beclin-1 CRISPR Activation Plasmid (h) provides a targeted, non-destructive approach to upregulating endogenous BECN1 expression without altering the underlying DNA sequence.
BECN1/Beclin-1 CRISPR Activation Plasmid (h) is a three-plasmid synergistic activation mediator (SAM) system engineered for highly efficient, site-specific transcriptional upregulation of the BECN1 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 BECN1 transcriptional start site, where VP64, p65, and HSF1 act in concert to recruit transcriptional machinery and drive upregulation of endogenous BECN1/Beclin-1 expression. Unlike nuclease-active Cas9, dCas9 does not introduce double-strand breaks or modify the genomic sequence, preserving the native BECN1 locus and enabling the study of BECN1/Beclin-1-dependent transcriptional responses at the endogenous locus, making it a valuable tool for functional studies, target gene identification, and the modeling of BECN1/Beclin-1 pathway restoration in tumor cells with silenced or reduced BECN1 expression.
