Human CANX encodes calnexin, an endoplasmic reticulum (ER) membrane lectin chaperone that binds monoglucosylated N-linked glycans to promote folding and quality control of nascent glycoproteins. Calnexin operates within the calnexin/calreticulin cycle alongside ERp57 to coordinate disulfide bond formation, retention of misfolded clients, and trafficking decisions in the secretory pathway. Through its role in ER proteostasis, CANX intersects with the unfolded protein response, ER-associated degradation (ERAD), and cellular stress signaling that can reshape antigen presentation and cell survival programs. Dysregulated calnexin-dependent folding and ER stress are frequently studied in the context of protein misfolding disorders, metabolic inflammation, and oncogenic secretory demands, making CANX a functional node for mechanistic pathway interrogation.
Calnexin Double Nickase Plasmid (h) consists of a matched pair of plasmids engineered for high-specificity editing of the CANX locus in human cell lines. Each plasmid expresses a Cas9 D10A nickase and a distinct sgRNA targeting opposite DNA strands within CANX. 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 CANX 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 CANX-disrupted clones.
