CC -!- FUNCTION: ADP:ATP antiporter that mediates import of ADP into the
CC mitochondrial matrix for ATP synthesis, and export of ATP out to fuel
CC the cell (By similarity). Cycles between the cytoplasmic-open state (c-
CC state) and the matrix-open state (m-state): operates by the alternating
CC access mechanism with a single substrate-binding site intermittently
CC exposed to either the cytosolic (c-state) or matrix (m-state) side of
CC the inner mitochondrial membrane (By similarity).
CC {ECO:0000250|UniProtKB:G2QNH0, ECO:0000250|UniProtKB:P48962}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=ADP(in) + ATP(out) = ADP(out) + ATP(in); Xref=Rhea:RHEA:34999,
CC ChEBI:CHEBI:30616, ChEBI:CHEBI:456216;
CC Evidence={ECO:0000250|UniProtKB:P48962};
CC PhysiologicalDirection=left-to-right; Xref=Rhea:RHEA:35000;
CC Evidence={ECO:0000250|UniProtKB:P48962};
CC -!- ACTIVITY REGULATION: The matrix-open state (m-state) is inhibited by
CC the membrane-permeable bongkrekic acid (BKA). The cytoplasmic-open
CC state (c-state) is inhibited by the membrane-impermeable toxic
CC inhibitor carboxyatractyloside (CATR). {ECO:0000250|UniProtKB:G2QNH0}.
CC -!- SUBUNIT: Monomer. {ECO:0000250|UniProtKB:G2QNH0,
CC ECO:0000250|UniProtKB:P02722}.
CC -!- SUBCELLULAR LOCATION: Mitochondrion inner membrane
CC {ECO:0000250|UniProtKB:P31167}; Multi-pass membrane protein
CC {ECO:0000255}.
CC -!- DOMAIN: The transmembrane helices are not perpendicular to the plane of
CC the membrane, but cross the membrane at an angle. At least 2 of the
CC odd-numbered transmembrane helices exhibit a sharp kink, due to the
CC presence of a conserved proline residue.
CC {ECO:0000250|UniProtKB:P18239}.
CC -!- SIMILARITY: Belongs to the mitochondrial carrier (TC 2.A.29) family.
CC {ECO:0000305}.
