LLGL1 encodes the human Hugl-1 protein, a conserved polarity regulator that supports epithelial organization by coordinating apical–basal polarity and junctional integrity. Hugl-1 functions within cell polarity networks that interface with cytoskeletal remodeling, vesicle trafficking, and spatial control of signaling, helping constrain inappropriate proliferation and migration. Disruption of LLGL1-dependent polarity is associated with loss of tissue architecture and altered differentiation programs, processes frequently implicated in tumor biology and invasive behavior. As a result, LLGL1 is widely studied in models of epithelial homeostasis, cell fate control, and mechanisms linking polarity to oncogenic signaling.
Hugl-1 Double Nickase Plasmid (h) consists of a matched pair of plasmids engineered for high-specificity editing of the LLGL1 locus in human cell lines. Each plasmid expresses a Cas9 D10A nickase and a distinct sgRNA targeting opposite DNA strands within LLGL1. 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 LLGL1 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 LLGL1-disrupted clones.
