FUT4 encodes alpha(1,3)-fucosyltransferase IV (FucT-IV), a Golgi-resident glycosyltransferase that catalyzes terminal fucosylation of glycans to generate Lewis-type carbohydrate epitopes on glycoproteins and glycolipids. By shaping cell-surface glycan architecture, FucT-IV influences selectin-dependent adhesion, leukocyte trafficking, and broader glycosylation-dependent signaling and receptor organization. FUT4 activity intersects with pathways governing cell–cell interactions, inflammation, and immune recognition through modulation of fucosylated ligands and glycan-mediated binding events. Dysregulated FUT4 expression and altered fucosylation patterns have been associated with changes in tumor cell adhesion, invasion, and immune evasion, making it a useful target for mechanistic studies of glycan remodeling in disease-relevant contexts.
FucT-IV Double Nickase Plasmid (h) consists of a matched pair of plasmids engineered for high-specificity editing of the FUT4 locus in human cell lines. Each plasmid expresses a Cas9 D10A nickase and a distinct sgRNA targeting opposite DNA strands within FUT4. 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 FUT4 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 FUT4-disrupted clones.
