CC -!- FUNCTION: Necessary for efficient export of extracytoplasmic CC proteins. Binds to the signal sequence when it emerges from the CC ribosomes. This binding is mediated at least in part by ribosomal CC protein L23 (Ref.8, Ref.9 and Ref.10). CC -!- SUBUNIT: Signal recognition particle consists of a 4.5 RNA CC molecule and protein ffh. CC -!- DOMAIN: The protein has a two domain structure: the G-domain binds CC GTP; the M-domain binds the RNA and also binds the signal CC sequence. CC -!- SIMILARITY: Belongs to the GTP-binding SRP family. CC -!- CAUTION: Ref.2 sequence differs from that shown due to a CC frameshift in position 100.
