Human ERO1A encodes the ER oxidoreductase Ero1-Lα, a FAD-dependent enzyme that reoxidizes protein disulfide isomerase (PDI) to sustain oxidative protein folding in the endoplasmic reticulum. By transferring electrons to molecular oxygen, Ero1-Lα contributes to disulfide bond formation and influences cellular redox balance, hydrogen peroxide production, and ER proteostasis. ERO1A activity intersects with unfolded protein response signaling and secretory pathway maturation, impacting processes such as glycoprotein assembly and quality control. Dysregulation of ERO1A has been linked in the literature to ER stress adaptation and redox remodeling in contexts including tumor biology and metabolic dysfunction, making it a useful target for mechanistic studies.
Ero1-Lα Double Nickase Plasmid (h) consists of a matched pair of plasmids engineered for high-specificity editing of the ERO1A locus in human cell lines. Each plasmid expresses a Cas9 D10A nickase and a distinct sgRNA targeting opposite DNA strands within ERO1A. 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 ERO1A 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 ERO1A-disrupted clones.
