DDX3X encodes an ATP-dependent DEAD-box RNA helicase that coordinates multiple steps of RNA metabolism, including pre-mRNA splicing, mRNA export, translation initiation, and stress granule dynamics. Through remodeling RNA–protein complexes, DDX3X integrates signaling cues that affect cell-cycle progression, innate immune sensing, and cellular stress responses. Dysregulation or mutation of DDX3X has been linked to neurodevelopmental phenotypes and has been recurrently observed across diverse cancer contexts, reflecting its broad influence on RNA processing and proteostasis. These properties make DDX3X a useful node for studying RNA helicase function, translational control, and pathways that couple RNA regulation to proliferation and stress adaptation.
DDX3X Double Nickase Plasmid (h) consists of a matched pair of plasmids engineered for high-specificity editing of the DDX3X locus in human cell lines. Each plasmid expresses a Cas9 D10A nickase and a distinct sgRNA targeting opposite DNA strands within DDX3X. 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 DDX3X 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 DDX3X-disrupted clones.
