RC STRAIN=PG1 {ECO:0000313|EMBL:CAE77051.1, RC ECO:0000313|Proteomes:UP000001016}; RX PubMed=14762060; DOI=10.1101/gr.1673304; RA Westberg J., Persson A., Holmberg A., Goesmann A., Lundeberg J., RA Johansson K.-E., Pettersson B., Uhlen M.; RT "The genome sequence of Mycoplasma mycoides subsp. mycoides SC type strain RT PG1T, the causative agent of contagious bovine pleuropneumonia (CBPP)."; RL Genome Res. 14:221-227(2004). CC -!- FUNCTION: Involved in targeting and insertion of nascent membrane CC proteins into the cytoplasmic membrane. Binds to the hydrophobic signal CC sequence of the ribosome-nascent chain (RNC) as it emerges from the CC ribosomes. The SRP-RNC complex is then targeted to the cytoplasmic CC membrane where it interacts with the SRP receptor FtsY. CC {ECO:0000256|HAMAP-Rule:MF_00306}. CC -!- SUBUNIT: Part of the signal recognition particle protein translocation CC system, which is composed of SRP and FtsY. {ECO:0000256|HAMAP- CC Rule:MF_00306}. CC -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000256|HAMAP-Rule:MF_00306}. CC Note=The SRP-RNC complex is targeted to the cytoplasmic membrane. CC {ECO:0000256|HAMAP-Rule:MF_00306}. CC -!- DOMAIN: Composed of three domains: the N-terminal N domain, which is CC responsible for interactions with the ribosome, the central G domain, CC which binds GTP, and the C-terminal M domain, which binds the RNA and CC the signal sequence of the RNC. {ECO:0000256|HAMAP-Rule:MF_00306}. CC -!- SIMILARITY: Belongs to the GTP-binding SRP family. SRP54 subfamily. CC {ECO:0000256|ARBA:ARBA00005450, ECO:0000256|HAMAP-Rule:MF_00306}.
