1 A novel adenine nucleotide translocase inhibitor, MT-21, induces cytochrome c release by a mitochondrial permeability transition-independent mechanism. MT 21 solute carrier family 25 member 6 Homo sapiens
2 We demonstrate that MT-21 significantly inhibits ADP transport activity in mitochondria and reduces binding of the adenine nucleotide translocase (ANT) to a phenylarsine oxide affinity matrix. MT 21 solute carrier family 25 member 6 Homo sapiens
3 We demonstrate that MT-21 significantly inhibits ADP transport activity in mitochondria and reduces binding of the adenine nucleotide translocase (ANT) to a phenylarsine oxide affinity matrix. MT 21 solute carrier family 25 member 6 Homo sapiens
4 In agreement with this, the MT-21-induced cytochrome c release was effectively inhibited in the presence of ANT ligands, and MT-21 could dissociate ANT from a complex with a glutathione S-transferase-cyclophilin D fusion protein. MT 21 solute carrier family 25 member 6 Homo sapiens
5 In agreement with this, the MT-21-induced cytochrome c release was effectively inhibited in the presence of ANT ligands, and MT-21 could dissociate ANT from a complex with a glutathione S-transferase-cyclophilin D fusion protein. MT 21 solute carrier family 25 member 6 Homo sapiens
6 In agreement with this, the MT-21-induced cytochrome c release was effectively inhibited in the presence of ANT ligands, and MT-21 could dissociate ANT from a complex with a glutathione S-transferase-cyclophilin D fusion protein. MT 21 solute carrier family 25 member 6 Homo sapiens
7 Interestingly, we also found that specific inhibitors of ANT such as MT-21 and atractyloside could induce cytochrome c release without mitochondrial swelling and that this event was highly dependent on the presence of Mg(2+). MT 21 solute carrier family 25 member 6 Homo sapiens
