OTUD7B (also known as Cezanne) encodes an OTU-family deubiquitinase that edits Lys11- and Lys63-linked ubiquitin chains to shape ubiquitin-dependent signaling and protein stability. By counteracting E3 ligase–driven ubiquitination, OTUD7B influences proteostasis and inflammatory signal transduction, including NF-κB pathway dynamics and related innate immune responses. OTUD7B activity has been connected to regulation of cytokine signaling networks and cellular stress adaptation, making it relevant to studies of immune dysregulation, tumor-associated inflammation, and ubiquitin pathway vulnerabilities. Functional perturbation of OTUD7B provides a route to dissect deubiquitination-dependent control points in transcriptional programs and receptor-proximal signaling complexes.
OTUD7B Double Nickase Plasmid (h) consists of a matched pair of plasmids engineered for high-specificity editing of the OTUD7B locus in human cell lines. Each plasmid expresses a Cas9 D10A nickase and a distinct sgRNA targeting opposite DNA strands within OTUD7B. 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 OTUD7B 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 OTUD7B-disrupted clones.
