α-gal A CRISPR Activation Plasmid (h) | sc-402562-ACT | 20 µg | $397.00 |
GLA encodes human α-galactosidase A (α-gal A), a lysosomal exoglycosidase that hydrolyzes terminal α-galactosyl residues from glycosphingolipids and related glycoconjugates. This activity supports lysosome-dependent lipid catabolism, intersects with endosomal–lysosomal trafficking, and influences cellular responses to lipid stress and autophagy. Altered GLA expression or enzymatic activity perturbs glycosphingolipid turnover and is strongly linked to lysosomal storage biology and downstream inflammatory and metabolic remodeling. As a result, GLA is frequently studied in the context of lysosome function, membrane lipid homeostasis, and cell-type-specific vulnerability in glycosphingolipid-associated disorders.
α-gal A CRISPR Activation Plasmid (h) provides a targeted, non-destructive approach to upregulating endogenous GLA expression without altering the underlying DNA sequence.
α-gal A CRISPR Activation Plasmid (h) is a three-plasmid synergistic activation mediator (SAM) system engineered for highly efficient, site-specific transcriptional upregulation of the GLA 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 GLA transcriptional start site, where VP64, p65, and HSF1 act in concert to recruit transcriptional machinery and drive upregulation of endogenous α-gal A expression. Unlike nuclease-active Cas9, dCas9 does not introduce double-strand breaks or modify the genomic sequence, preserving the native GLA locus and enabling the study of α-gal A-dependent transcriptional responses at the endogenous locus, making it a valuable tool for functional studies, target gene identification, and the modeling of α-gal A pathway restoration in tumor cells with silenced or reduced GLA expression.
