AARS2 encodes the mitochondrial alanyl-tRNA synthetase, an essential enzyme that charges tRNA(Ala) to support accurate translation of mitochondrially encoded proteins. By sustaining mitochondrial ribosome function, AARS2 contributes to oxidative phosphorylation, respiratory chain biogenesis, and overall mitochondrial proteostasis. Disruption of AARS2-dependent aminoacylation perturbs cellular energy metabolism and can trigger compensatory stress responses linked to mitochondrial dysfunction. Variants in AARS2 have been associated with human mitochondrial disease phenotypes, making it a relevant target for studying genotype–mitochondria relationships in metabolically active tissues.
AARS2 Double Nickase Plasmid (h) consists of a matched pair of plasmids engineered for high-specificity editing of the AARS2 locus in human cell lines. Each plasmid expresses a Cas9 D10A nickase and a distinct sgRNA targeting opposite DNA strands within AARS2. 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 AARS2 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 AARS2-disrupted clones.
