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). Interaction with SRP-RNC leads to the
CC       transfer of the RNC complex to the Sec translocase for insertion into
CC       the membrane, the hydrolysis of GTP by both Ffh and FtsY, and the
CC       dissociation of the SRP-FtsY complex into the individual components.
CC       {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. SRP is a ribonucleoprotein
CC       composed of Ffh and a 4.5S RNA molecule. {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}.
