Fancd2 encodes FANCD2, a central effector of the Fanconi anemia (FA) DNA interstrand crosslink repair pathway that protects genome stability during replication stress. Upon DNA damage, FANCD2 is monoubiquitinated with FANCI and recruited to stalled replication forks, coordinating nucleolytic processing, homologous recombination, and interactions with BRCA-associated repair factors. This activity supports S-phase checkpoint control, limits chromosomal breakage, and preserves replication fork integrity. Disruption of FANCD2-dependent repair is linked to Fanconi anemia biology and hypersensitivity to crosslinking agents, making Fancd2 a key locus for studying replication-coupled DNA repair and genome maintenance in mouse models.
FANCD2 Double Nickase Plasmid (m) consists of a matched pair of plasmids engineered for high-specificity editing of the Fancd2 locus in mouse cell lines. Each plasmid expresses a Cas9 D10A nickase and a distinct sgRNA targeting opposite DNA strands within Fancd2. 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 Fancd2 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 Fancd2-disrupted clones.
