Mouse Aco1 encodes iron regulatory protein 1 (IRP-1), a bifunctional cytosolic protein that switches between an aconitase enzyme and an RNA-binding regulator depending on cellular iron–sulfur cluster status. In its RNA-binding form, IRP-1 recognizes iron-responsive elements in target mRNAs to coordinate iron uptake, storage, and utilization by modulating transcripts such as transferrin receptor and ferritin. This post-transcriptional network integrates with mitochondrial iron–sulfur biogenesis, oxidative stress responses, and metabolic rewiring during iron limitation. Dysregulated IRP-1 activity perturbs iron homeostasis and redox balance, making Aco1 a key node for studying anemia-like phenotypes, neurodegeneration-associated iron accumulation, and inflammation-linked metabolic stress in model systems.
IRP-1 Double Nickase Plasmid (m) consists of a matched pair of plasmids engineered for high-specificity editing of the Aco1 locus in mouse cell lines. Each plasmid expresses a Cas9 D10A nickase and a distinct sgRNA targeting opposite DNA strands within Aco1. 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 Aco1 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 Aco1-disrupted clones.
