Human CRYGC encodes γC-crystallin, a highly abundant structural protein in the ocular lens that contributes to refractive index, transparency, and long-term fiber cell stability. As a member of the β/γ-crystallin superfamily, γC-crystallin supports tight protein packing and resistance to aggregation, processes central to proteostasis in the largely organelle-free lens fiber cell environment. Perturbations in crystallin folding and solubility intersect with oxidative stress responses and chaperone-dependent maintenance of lens proteins, linking disrupted homeostasis to light-scattering aggregates. Genetic variation or dysregulated stability of γC-crystallin is associated with inherited lens opacity phenotypes, providing a molecular entry point for studying cataract-relevant mechanisms.
γC-crystallin Double Nickase Plasmid (h) consists of a matched pair of plasmids engineered for high-specificity editing of the CRYGC locus in human cell lines. Each plasmid expresses a Cas9 D10A nickase and a distinct sgRNA targeting opposite DNA strands within CRYGC. 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 CRYGC 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 CRYGC-disrupted clones.
