OPTN encodes optineurin, a ubiquitin-binding adaptor that integrates selective autophagy, vesicular trafficking, and innate immune signaling. Optineurin functions as an autophagy receptor during xenophagy and mitophagy by linking ubiquitinated cargo to LC3 family proteins, and it modulates NF-κB and TBK1/IRF3-dependent antiviral pathways. It also contributes to Golgi maintenance and membrane dynamics through interactions with myosin VI, Rab GTPases, and ubiquitin chain complexes. Dysregulation or mutation of OPTN has been associated with neurodegeneration and glaucoma-related phenotypes, making it a widely studied node in proteostasis and inflammatory signaling networks.
Optineurin Double Nickase Plasmid (h) consists of a matched pair of plasmids engineered for high-specificity editing of the OPTN locus in human cell lines. Each plasmid expresses a Cas9 D10A nickase and a distinct sgRNA targeting opposite DNA strands within OPTN. 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 OPTN 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 OPTN-disrupted clones.
