RL Submitted (JUN-1999) to the EMBL/GenBank/DDBJ databases.
CC -!- FUNCTION: UCP are mitochondrial transporter proteins that create proton
CC leaks across the inner mitochondrial membrane, thus uncoupling
CC oxidative phosphorylation from ATP synthesis. As a result, energy is
CC dissipated in the form of heat (By similarity). {ECO:0000250}.
CC -!- SUBUNIT: Acts as a dimer forming a proton channel. {ECO:0000250}.
CC -!- SUBCELLULAR LOCATION: Mitochondrion inner membrane; Multi-pass membrane
CC protein.
CC -!- SIMILARITY: Belongs to the mitochondrial carrier (TC 2.A.29) family.
CC {ECO:0000305}.
