TIPARP encodes PARP-7, a mono-ADP-ribosyltransferase that catalyzes MARylation of protein substrates to modulate signaling, transcriptional programs, and proteostasis. PARP-7 is induced by aryl hydrocarbon receptor (AHR) activity and functions within xenobiotic response pathways, providing feedback control over receptor-dependent gene expression and stress-adaptive responses. Through regulation of interferon-associated signaling, ubiquitin–proteasome dynamics, and nuclear transcriptional complexes, PARP-7 influences innate immune tone and cellular adaptation to environmental cues. Dysregulated TIPARP/PARP-7 activity has been linked in the literature to altered inflammatory signaling and oncogenic phenotypes, supporting its relevance for mechanistic studies in cancer biology and immune regulation.
PARP-7 Double Nickase Plasmid (h) consists of a matched pair of plasmids engineered for high-specificity editing of the TIPARP locus in human cell lines. Each plasmid expresses a Cas9 D10A nickase and a distinct sgRNA targeting opposite DNA strands within TIPARP. 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 TIPARP 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 TIPARP-disrupted clones.
