Eun Koh. NIH Adenine nucleotide translocator (ANT), also known as the ADP/ATP translocase(ANT), ADP/ATP carrier protein (AAC) or mitochondrial ADP/ATP carrier, exchanges free ATP with free ADP across the inner mitochondrial membrane. Therefore, proper function of ANT is essential for the transfer of ATP synthesized in mitochondria to the cytoplasm. ADP/ATP translocase transports ATP synthesized from oxidative phosphorylation into the cytoplasm, where it can be used as the principal energy currency of the cell to power thermodynamically unfavorable reactions. Adenine Nucleotide Translocase (ANT) The ANT is an ADP/ATP exchanger and is the most abundant protein on the mitochondrial inner membrane. Therefore it is the key link between ATP production in the mitochondrial matrix space and ATP consumption in the cytosol. ANT1 functions in mitochondria, which are structures within cells that convert the energy from food into a form that cells can use. In revealing the link between ANT and mitophagy, and the impact mutations have on quality control, our findings change the way we think about the disease-causing mutations and enable us to focus our attention on the right pathway.

Recent studies have shown that mutations in the adenine nucleotide translocase (Ant) cause aging-dependent degenerative cell de ath (DCD) in yeast, which is sequentially manifested by inner membrane stress, mitochondrial DNA (mtDNA) loss, and progressive loss of cell viability. Bisindolylpyrrole triggers transient mitochondrial permeability transitions to cause apoptosis in a VDAC1/2 and cyclophilin D-dependent manner via the ANT-associated pore. Oxidative stress activates the MPTP by glutathione-mediated cross-linking of Cys(159) and Cys(256) on matrix-facing loops of the ANT that inhibits ADP binding and enhances CyP-D binding. Oxidative Stress, Neuroinflammation and Mitochondria in the Pathophysiology of Amyotrophic Lateral Sclerosis.
