CUL3 encodes cullin-3 (CUL-3), a core scaffold of CRL3 E3 ubiquitin ligase complexes that recruit BTB-domain substrate adaptors to direct ubiquitin-dependent proteasomal turnover. Through regulated degradation of signaling and stress-response proteins, CUL-3 helps control cell cycle progression, oxidative stress pathways (including KEAP1–NRF2), cytoskeletal dynamics, and innate immune signaling. Altered CUL3 activity can rewire protein homeostasis and transcriptional programs, influencing pathways linked to oncogenic signaling, neurodevelopment, and cellular stress adaptation. In human genetics, CUL3 variants and CRL3 dysregulation are associated with hypertension-related mechanisms and broader disease-relevant changes in ubiquitin signaling.
CUL-3 Double Nickase Plasmid (h) consists of a matched pair of plasmids engineered for high-specificity editing of the CUL3 locus in human cell lines. Each plasmid expresses a Cas9 D10A nickase and a distinct sgRNA targeting opposite DNA strands within CUL3. 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 CUL3 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 CUL3-disrupted clones.
