Adenine nucleotide transporter involved in the uniport of ATP and adenine nucleotide hetero-exchange transport between the cytosol and the peroxisomal lumen. This transport is accompanied by a proton transport from the peroxisomal lumen to the cytosol. Transport of ATP into the peroxisome is required for beta-oxidation of medium-chain fatty acids. Required for growth on medium-chain fatty acids, pH gradient formation in peroxisomes and for normal peroxisome proliferation. Induced by oleic acid, through its ORE-like (oleate responsive element) promoter element and the PIP2-OAF1 transcription factors. Present with 2250 molecules/cell in log phase SD medium. Belongs to the mitochondrial carrier (TC 2.A.29) family.
