Parp9 encodes PARP-9, a mono-ADP-ribosyltransferase–family member that functions predominantly as a regulatory scaffold in interferon-stimulated signaling. PARP-9 partners with DTX3L to promote ubiquitin-dependent pathways that shape antiviral responses, antigen presentation, and transcriptional programs downstream of JAK–STAT and innate immune receptors. In immune and hematopoietic cells, PARP-9 influences inflammatory gene expression, macrophage polarization, and cellular responses to pathogen- or cytokine-driven stress. Dysregulated PARP9 activity and expression have been associated with altered immune signaling and tumor-immune interactions, supporting its relevance in studies of inflammation, infection biology, and cancer-related immune regulation.
PARP-9 Double Nickase Plasmid (m) consists of a matched pair of plasmids engineered for high-specificity editing of the Parp9 locus in mouse cell lines. Each plasmid expresses a Cas9 D10A nickase and a distinct sgRNA targeting opposite DNA strands within Parp9. 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 Parp9 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 Parp9-disrupted clones.
