CC   -!- FUNCTION: Component of the type II secretion system inner membrane
CC       complex required for the energy-dependent secretion of extracellular
CC       factors such as proteases and toxins from the periplasm.
CC       {ECO:0000250|UniProtKB:Q00514}.
CC   -!- SUBUNIT: Type II secretion system is composed of four main components:
CC       the outer membrane complex, the inner membrane complex, the cytoplasmic
CC       secretion ATPase and the periplasm-spanning pseudopilus (By
CC       similarity). Homodimer (By similarity). Interacts with PulE and PulL
CC       components (By similarity). {ECO:0000250|UniProtKB:P45780,
CC       ECO:0000250|UniProtKB:Q00513, ECO:0000250|UniProtKB:Q00514}.
CC   -!- SUBCELLULAR LOCATION: Cell inner membrane {ECO:0000305}; Multi-pass
CC       membrane protein {ECO:0000305}.
CC   -!- SIMILARITY: Belongs to the GSP F family. {ECO:0000305}.
