CC -!- FUNCTION: Resistance to tetracycline by an active tetracycline efflux. CC This is an energy-dependent process that decreases the accumulation of CC the antibiotic in whole cells. This protein functions as a metal- CC tetracycline/H(+) antiporter. CC -!- SUBCELLULAR LOCATION: Cell inner membrane; Multi-pass membrane protein. CC -!- BIOTECHNOLOGY: This protein is used as a marker in many commonly used CC cloning vectors, such as pBR322 and pACYC184. CC -!- SIMILARITY: Belongs to the major facilitator superfamily. TCR/Tet CC family. {ECO:0000305}.
