Abstract The mitochondrial adenine nucleotide translocator (ANT) catalyses the exchange of ATP and ADP between the mitochondria and the cytosol. We have cloned and sequenced the gene encoding the Dictyostelium discoideum ANT (DdANT) and analysed its transcriptional regulation. The single copy D. discoideum ant gene encodes a protein of 309 amino acid residues with a predicted molecular mass of 33,469 Da and a pI of 9.85. These values are comparable to those of ANTs from mammals, insects and fungi. The long N-terminal extension characteristic of plant ANT is absent in DdANT. The protein coding region of the D. discoideum ant gene is interrupted by three introns. Polyclonal antibodies directed against the beef heart mitochondrial ANT or its C-terminal peptide recognized the D. discoideum protein. Northern blot analysis revealed that the expression of the D. discoideum ant gene decreased rapidly during the first hours of multicellular development but the amount of protein remained stable throughout differentiation.
