Uhrf1 encodes UHRF1, a multidomain epigenetic regulator that couples recognition of hemimethylated CpG DNA with recruitment of maintenance DNA methylation machinery during S phase. Through its SRA, PHD, and RING domains, UHRF1 coordinates DNA methylation inheritance, histone modification crosstalk, and chromatin remodeling to preserve genome stability and transcriptional programs. In mouse cells, UHRF1 activity is tightly linked to cell-cycle progression, replication-coupled chromatin assembly, and repression of transposable elements, with downstream effects on differentiation and lineage commitment. Dysregulated UHRF1-associated epigenetic maintenance is broadly relevant to oncogenic transformation, aberrant proliferation, and epigenome instability, making Uhrf1 a key node for mechanistic studies of methylation-driven gene regulation.
UHRF1 Double Nickase Plasmid (m) consists of a matched pair of plasmids engineered for high-specificity editing of the Uhrf1 locus in mouse cell lines. Each plasmid expresses a Cas9 D10A nickase and a distinct sgRNA targeting opposite DNA strands within Uhrf1. 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 Uhrf1 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 Uhrf1-disrupted clones.
