Human ADPRHL2 encodes ARH3, an ADP-ribosylhydrolase that removes serine-linked mono- and poly(ADP-ribose) from proteins to reverse PARP-dependent ADP-ribosylation. Through this activity, ARH3 helps regulate DNA damage signaling and repair, chromatin dynamics, and stress-response pathways that depend on reversible ADP-ribose modifications. ARH3 functions in coordination with PARP1/2 and related ADP-ribosylation enzymes to maintain proteome homeostasis following genotoxic and oxidative stress. Altered ADPRHL2 function has been linked to neurodegeneration and stress-induced cellular vulnerability, making it a relevant target for studying genome stability and neuronal resilience mechanisms.
ARH3 Double Nickase Plasmid (h) consists of a matched pair of plasmids engineered for high-specificity editing of the ADPRHL2 locus in human cell lines. Each plasmid expresses a Cas9 D10A nickase and a distinct sgRNA targeting opposite DNA strands within ADPRHL2. 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 ADPRHL2 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 ADPRHL2-disrupted clones.
