LYAG CRISPR Activation Plasmid (h) | sc-402385-ACT | 20 µg | $397.00 |
Human GAA encodes lysosomal alpha-glucosidase, a hydrolase required for glycogen catabolism within the endolysosomal system. By converting glycogen to glucose, GAA supports cellular energy homeostasis and prevents lysosomal glycogen accumulation that can disrupt autophagy and broader lysosome-dependent quality control pathways. Reduced GAA activity is linked to lysosomal storage pathology characterized by glycogen buildup and secondary effects on muscle and cardiac cell function. As a result, GAA/LYAG biology is frequently studied in models of lysosomal function, metabolic stress responses, and glycogen handling across diverse cell types.
LYAG CRISPR Activation Plasmid (h) provides a targeted, non-destructive approach to upregulating endogenous GAA expression without altering the underlying DNA sequence.
LYAG CRISPR Activation Plasmid (h) is a three-plasmid synergistic activation mediator (SAM) system engineered for highly efficient, site-specific transcriptional upregulation of the GAA 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 GAA transcriptional start site, where VP64, p65, and HSF1 act in concert to recruit transcriptional machinery and drive upregulation of endogenous LYAG expression. Unlike nuclease-active Cas9, dCas9 does not introduce double-strand breaks or modify the genomic sequence, preserving the native GAA locus and enabling the study of LYAG-dependent transcriptional responses at the endogenous locus, making it a valuable tool for functional studies, target gene identification, and the modeling of LYAG pathway restoration in tumor cells with silenced or reduced GAA expression.
