RL Submitted (OCT-1995) to the EMBL/GenBank/DDBJ databases.
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}.
