DNA damage regulated autophagy modulator 1 (DRAM1) encodes DRAM, a lysosomal membrane protein transcriptionally induced by TP53 that links stress signaling to autophagy and lysosome-dependent turnover. DRAM1 supports autophagosome maturation, lysosomal acidification, and autophagic flux, thereby influencing metabolic adaptation, mitochondrial quality control, and cell fate decisions. Through its roles in autophagy–apoptosis crosstalk and lysosomal pathways, altered DRAM1 activity has been associated with dysregulated stress responses observed in cancer biology and inflammatory contexts. DRAM1 is therefore widely studied as a node connecting TP53 signaling, lysosomal function, and autophagy-associated homeostasis.
DRAM CRISPR Activation Plasmid (h) provides a targeted, non-destructive approach to upregulating endogenous DRAM1 expression without altering the underlying DNA sequence.
DRAM CRISPR Activation Plasmid (h) is a three-plasmid synergistic activation mediator (SAM) system engineered for highly efficient, site-specific transcriptional upregulation of the DRAM1 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 DRAM1 transcriptional start site, where VP64, p65, and HSF1 act in concert to recruit transcriptional machinery and drive upregulation of endogenous DRAM expression. Unlike nuclease-active Cas9, dCas9 does not introduce double-strand breaks or modify the genomic sequence, preserving the native DRAM1 locus and enabling the study of DRAM-dependent transcriptional responses at the endogenous locus, making it a valuable tool for functional studies, target gene identification, and the modeling of DRAM pathway restoration in tumor cells with silenced or reduced DRAM1 expression.
