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 (By similarity). Belongs to the mitochondrial carrier (TC 2.A.29) family.
