CC   -!- FUNCTION: Binds to the signal sequence of presecretory protein when
CC       they emerge from the ribosomes and transfers them to TRAM
CC       (translocating chain-associating membrane protein).
CC   -!- SUBUNIT: Signal recognition particle consists of a 7S RNA molecule of
CC       300 nucleotides and six protein subunits: SRP72, SRP68, SRP54, SRP19,
CC       SRP14 and SRP9.
CC   -!- SUBCELLULAR LOCATION: Cytoplasm.
CC   -!- DOMAIN: Has a two domain structure: the G-domain binds GTP; the M-
CC       domain binds the 7S RNA in presence of SRP19 and also binds the signal
CC       sequence.
CC   -!- SIMILARITY: Belongs to the GTP-binding SRP family. SRP54 subfamily.
CC       {ECO:0000305}.
