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). Specifically required
CC during spermatogenesis, probably to mediate ADP:ATP exchange in
CC spermatocytes. Large ATP supplies from mitochondria may be critical for
CC normal progression of spermatogenesis during early stages of meiotic
CC prophase I, including DNA double-strand break repair and chromosomal
CC synapsis. In addition to its ADP:ATP antiporter activity, also involved
CC in mitochondrial uncoupling and mitochondrial permeability transition
CC pore (mPTP) activity (By similarity). Plays a role in mitochondrial
CC uncoupling by acting as a proton transporter: proton transport
CC uncouples the proton flows via the electron transport chain and ATP
CC synthase to reduce the efficiency of ATP production and cause
CC mitochondrial thermogenesis. Proton transporter activity is inhibited
CC by ADP:ATP antiporter activity, suggesting that SLC25A31/ANT4 acts as a
CC master regulator of mitochondrial energy output by maintaining a
CC delicate balance between ATP production (ADP:ATP antiporter activity)
CC and thermogenesis (proton transporter activity). Proton transporter
CC activity requires free fatty acids as cofactor, but does not transport
CC it (By similarity). Also plays a key role in mPTP opening, a non-
CC specific pore that enables free passage of the mitochondrial membranes
CC to solutes of up to 1.5 kDa, and which contributes to cell death. It is
CC however unclear if SLC25A31/ANT4 constitutes a pore-forming component
CC of mPTP or regulates it (By similarity). {ECO:0000250|UniProtKB:G2QNH0,

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) (By similarity). Proton
CC transporter activity is inhibited by ADP:ATP antiporter activity (By
CC similarity). {ECO:0000250|UniProtKB:G2QNH0,

CC -!- SUBCELLULAR LOCATION: Mitochondrion inner membrane
CC {ECO:0000250|UniProtKB:P02722}; Multi-pass membrane protein
CC {ECO:0000255}. Membrane {ECO:0000250|UniProtKB:Q9H0C2}; Multi-pass
CC membrane protein {ECO:0000255}. Cell projection, cilium, flagellum
CC membrane {ECO:0000250|UniProtKB:Q3V132}; Multi-pass membrane protein
CC {ECO:0000255}. Note=In sperm flagellum this protein is located in the
CC fibrous sheath, a non-mitochondrial region (By similarity). May
CC localize to non-mitochondrial membranes (By similarity).
CC {ECO:0000250|UniProtKB:Q9H0C2}.
CC -!- DOMAIN: The transmembrane helices are not perpendicular to the plane of
CC the membrane, but cross the membrane at an angle. Odd-numbered
CC transmembrane helices exhibit a sharp kink, due to the presence of a
CC conserved proline residue. {ECO:0000250|UniProtKB:P02722}.
CC -!- SIMILARITY: Belongs to the mitochondrial carrier (TC 2.A.29) family.
CC {ECO:0000305}.
