DHX33 (DDX33) encodes a human DEAD-box RNA helicase that couples ATP-dependent RNA remodeling to ribosome biogenesis and RNA metabolism. DDX33 has been implicated in nucleolar function, rRNA transcription/processing, and coordination of translation capacity with proliferative signaling, linking RNA homeostasis to cell-cycle progression. Beyond housekeeping roles, DDX33 participates in innate immune sensing pathways by supporting RNA-dependent signaling and can influence inflammatory transcriptional programs. Dysregulated DDX33 expression or activity has been associated with altered growth control and stress responses in cancer-relevant contexts, making it a useful node for dissecting RNA processing–driven phenotypes.
DDX33 Double Nickase Plasmid (h) consists of a matched pair of plasmids engineered for high-specificity editing of the DHX33 locus in human cell lines. Each plasmid expresses a Cas9 D10A nickase and a distinct sgRNA targeting opposite DNA strands within DHX33. 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 DHX33 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 DHX33-disrupted clones.
