Human DHPS encodes deoxyhypusine synthase (DHS), an essential NAD-dependent enzyme that catalyzes the first step of hypusination by transferring an aminobutyl moiety from spermidine to eIF5A, generating deoxyhypusine. This post-translational modification is required for eIF5A activity and supports translation elongation, protein synthesis control, and cell-cycle progression, linking polyamine metabolism to proteostasis. DHS function intersects with pathways governing cellular growth and stress responses, and perturbation of the DHPS–eIF5A hypusination axis has been associated with dysregulated proliferation and neurodevelopmental phenotypes. Because hypusination impacts selective translation of difficult-to-synthesize motifs, DHPS is frequently studied in the context of metabolic rewiring, proteotoxic stress, and mechanisms that maintain tissue homeostasis.
DHS Double Nickase Plasmid (h) consists of a matched pair of plasmids engineered for high-specificity editing of the DHPS locus in human cell lines. Each plasmid expresses a Cas9 D10A nickase and a distinct sgRNA targeting opposite DNA strands within DHPS. 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 DHPS 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 DHPS-disrupted clones.
