TOMM70 encodes Tom70, an outer mitochondrial membrane import receptor that recognizes cytosolic preproteins and chaperone-bound hydrophobic carriers, coordinating their delivery to the TOM complex for translocation into mitochondria. By supporting biogenesis of respiratory chain components and mitochondrial proteostasis, Tom70 contributes to oxidative phosphorylation capacity, organelle dynamics, and cellular stress adaptation. Altered TOMM70 function has been studied in contexts of mitochondrial dysfunction and neurodegeneration, and it can influence innate immune signaling at mitochondria by modulating the availability and organization of imported factors that interface with MAVS-dependent antiviral pathways. These features make TOMM70 a useful target for investigating mitochondrial protein import, metabolic remodeling, and stress-response circuitry relevant to complex disease phenotypes.
Tom70 Double Nickase Plasmid (h) consists of a matched pair of plasmids engineered for high-specificity editing of the TOMM70 locus in human cell lines. Each plasmid expresses a Cas9 D10A nickase and a distinct sgRNA targeting opposite DNA strands within TOMM70. 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 TOMM70 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 TOMM70-disrupted clones.
