AATC Double Nickase Plasmid (h) | sc-405477-NIC | 20 µg | $410.00 |
Human GOT1 encodes cytosolic aspartate aminotransferase (AATC), a pyridoxal phosphate–dependent enzyme that catalyzes reversible transamination between aspartate and α-ketoglutarate to generate oxaloacetate and glutamate. This activity links amino acid metabolism to the malate–aspartate shuttle, supporting NADH redox balance, anaplerosis, and carbon flux into the TCA cycle. GOT1 function interfaces with nitrogen handling and glutamate/aspartate pools that influence biosynthetic programs and cellular stress responses. Dysregulation of GOT1-associated metabolic routing has been studied in contexts of altered bioenergetics and redox homeostasis relevant to proliferative and degenerative disease mechanisms.
AATC Double Nickase Plasmid (h) consists of a matched pair of plasmids engineered for high-specificity editing of the GOT1 locus in human cell lines. Each plasmid expresses a Cas9 D10A nickase and a distinct sgRNA targeting opposite DNA strands within GOT1. 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 GOT1 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 GOT1-disrupted clones.
