CC   -!- FUNCTION: Inner membrane component of the type II secretion system
CC       required for the energy-dependent secretion of extracellular factors
CC       such as proteases and toxins from the periplasm. Plays a role in the
CC       complex assembly and recruits XpsM resulting in a stable complex in the
CC       inner membrane. Provides thus a link between the energy-providing XpsE
CC       protein in the cytoplasm and the rest of the T2SS machinery.
CC       {ECO:0000250|UniProtKB:P25060}.
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). Forms homodimers. Interacts with XpsM/GspM. Interacts with
CC       XpsE/GspE and XpsF/GspF (By similarity). {ECO:0000250|UniProtKB:P25060,
CC       ECO:0000250|UniProtKB:Q00514}.
CC   -!- SUBCELLULAR LOCATION: Cell inner membrane
CC       {ECO:0000250|UniProtKB:P25060}; Single-pass membrane protein
CC       {ECO:0000250|UniProtKB:P25060}.
CC   -!- SIMILARITY: Belongs to the GSP L family. {ECO:0000305}.
