DTX1 encodes Deltex-1, a RING-type E3 ubiquitin ligase that functions as a context-dependent regulator of NOTCH signaling and downstream transcriptional programs controlling cell fate decisions. Deltex-1 participates in protein ubiquitination and endocytic trafficking events that modulate receptor turnover and signal duration, linking NOTCH pathway output to differentiation and immune cell homeostasis. Altered DTX1 activity has been associated with dysregulated NOTCH-dependent gene expression and aberrant lymphocyte activation states, making it relevant to studies of hematologic malignancy biology and inflammatory signaling. As a nodal regulator of pathway amplitude, Deltex-1 is also used to interrogate crosstalk between ubiquitin-mediated proteostasis, transcriptional control, and developmental signaling networks.
Deltex-1 Double Nickase Plasmid (h) consists of a matched pair of plasmids engineered for high-specificity editing of the DTX1 locus in human cell lines. Each plasmid expresses a Cas9 D10A nickase and a distinct sgRNA targeting opposite DNA strands within DTX1. 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 DTX1 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 DTX1-disrupted clones.
