Mouse Upf1 (Rent1) encodes an ATP-dependent RNA helicase that is central to nonsense-mediated mRNA decay (NMD), a conserved RNA surveillance pathway that recognizes premature termination codons and promotes degradation of aberrant transcripts. UPF1 coordinates with translation termination factors and SMG proteins to trigger mRNP remodeling, RNA decay, and regulation of transcriptome quality control. Beyond canonical NMD, UPF1 contributes to mRNA turnover, replication stress responses, and genome stability through interactions with RNA processing and DNA damage response networks. Dysregulated UPF1 activity has been linked to altered proteostasis and stress signaling in models of neurodevelopmental dysfunction, cancer biology, and inflammatory regulation, supporting its use in pathway-focused mechanistic studies.
Rent1 Double Nickase Plasmid (m) consists of a matched pair of plasmids engineered for high-specificity editing of the Upf1 locus in mouse cell lines. Each plasmid expresses a Cas9 D10A nickase and a distinct sgRNA targeting opposite DNA strands within Upf1. 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 Upf1 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 Upf1-disrupted clones.
