CC   -!- FUNCTION: Involved in targeting and insertion of nascent membrane
CC       proteins into the cytoplasmic membrane. Acts as a receptor for the
CC       complex formed by the signal recognition particle (SRP) and the
CC       ribosome-nascent chain (RNC). {ECO:0000255|HAMAP-Rule:MF_00920}.
CC   -!- SUBUNIT: Part of the signal recognition particle protein translocation
CC       system, which is composed of SRP and FtsY. {ECO:0000255|HAMAP-
CC       Rule:MF_00920}.
CC   -!- SUBCELLULAR LOCATION: Cell membrane; Peripheral membrane protein;
CC       Cytoplasmic side. Cytoplasm {ECO:0000255|HAMAP-Rule:MF_00920}.
CC   -!- SIMILARITY: Belongs to the GTP-binding SRP family. FtsY subfamily.
CC       {ECO:0000255|HAMAP-Rule:MF_00920}.
