Summary: Enables ATP:ADP antiporter activity. Involved in several processes, including adenine nucleotide transport; cellular respiration; and heme transport. Located in mitochondrial inner membrane. Used to study autosomal dominant progressive external ophthalmoplegia with mitochondrial DNA deletions 2. Human ortholog(s) of this gene implicated in intrinsic cardiomyopathy (multiple); mitochondrial DNA depletion syndrome (multiple); and mitochondrial myopathy (multiple). Orthologous to several human genes including SLC25A4 (solute carrier family 25 member 4) and SLC25A5 (solute carrier family 25 member 5). [provided by Alliance of Genome Resources, Apr 2022]

Yeast aac2 R96H and aac2 R252G mutations are equivalent to R80H and R235G human ANT1 pathological mutations. mtDNA instability induced by aac2R96H and aac2R252G is rescued by N-acetylcysteine.
Title: Dominance of yeast aac2(R96H) and aac2(R252G) mutations, equivalent to pathological mutations in ant1, is due to gain of function.
Mutations in yeast Aac2, equivalent to those in human Ant1 in progressive external ophthalmoplegia, cause protein misfolding. Misfolded Aac2 affects assembly & stability of multiple protein complexes in membrane, which ultimately inhibits cell growth
Title: Misfolding of mutant adenine nucleotide translocase in yeast supports a novel mechanism of Ant1-induced muscle diseases.
The protective role of cathepsin D in acetic acid-induced apoptosis depends on ANT (Aac2p) but not on the voltage-dependent channel (Por1p).

Pathogenic mutations likely enhance the intrinsic proton-conducting activity of adenine nucleotide translocase Aac2, which excessively uncouples the mitochondrial inner membrane thereby affecting energy transduction and mitochondrial biogenesis.

Tyr203 and Phe208, aromatic residues of Anc2 transmembrane domain 4 protein carrier, may play a role in nucleotide attraction and its progress through the carrier leading to a productive adenosine diphosphate/adenosine triphosphate exchange.

Preferred Names: ADP/ATP carrier protein PET9

NP_009523.1

Major ADP/ATP carrier of the mitochondrial inner membrane; exchanges cytosolic ADP for mitochondrially synthesized ATP; also imports heme and ATP; also functions in peroxisomes; required for viability in many lab strains that carry a sal1 mutation; PET9 has a paralog, AAC3, that arose from the whole genome duplication; human homolog SLC25A4 implicated in progressive external ophthalmoplegia can complement yeast null mutant
