GLA encodes human α-galactosidase A (α-gal A), a lysosomal exoglycosidase that hydrolyzes terminal α-galactosyl residues from glycosphingolipids and other glycoconjugates. By participating in lysosomal catabolism and sphingolipid turnover, α-gal A supports membrane lipid homeostasis and limits accumulation of glycolipid substrates that can perturb endolysosomal trafficking and cellular stress responses. Loss or reduction of GLA activity is associated with Fabry disease, a lysosomal storage disorder characterized by progressive substrate deposition and downstream inflammatory and vascular pathology. Consequently, GLA is widely studied in the context of lysosome biology, glycosphingolipid metabolism, and mechanisms linking impaired degradation to cellular dysfunction.
α-gal A Double Nickase Plasmid (h) consists of a matched pair of plasmids engineered for high-specificity editing of the GLA locus in human cell lines. Each plasmid expresses a Cas9 D10A nickase and a distinct sgRNA targeting opposite DNA strands within GLA. When directed to adjacent sites on opposite DNA strands, the two nickases generate offset single-strand nicks that together produce a staggered double-strand break, requiring coordinated on-target activity from both guides. The resulting DNA break is resolved by endogenous cellular repair pathways, most commonly through non-homologous end joining (NHEJ), leading to insertions or deletions that disrupt GLA function. By requiring dual sgRNA engagement at the target locus, the double nicking approach enhances editing specificity and provides a complementary CRISPR strategy for applications where additional control over targeting precision is desired.
To support efficient identification of edited cells, one plasmid encodes GFP for fluorescent visualization of transfected populations, while the companion plasmid carries a puromycin resistance gene for antibiotic selection. Together, these features support efficient enrichment of co-transfected populations and simplify the validation of GLA-disrupted clones.
