CC   -!- FUNCTION: Involved in targeting and insertion of nascent membrane
CC       proteins into the cytoplasmic membrane. Binds directly to 7S RNA and
CC       mediates binding of the 54 kDa subunit of the SRP. {ECO:0000255|HAMAP-
CC       Rule:MF_00305}.
CC   -!- SUBUNIT: Part of the signal recognition particle protein translocation
CC       system, which is composed of SRP and FtsY. Archaeal SRP consists of a
CC       7S RNA molecule of 300 nucleotides and two protein subunits: SRP54 and
CC       SRP19. {ECO:0000255|HAMAP-Rule:MF_00305}.
CC   -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000255|HAMAP-Rule:MF_00305}.
CC   -!- SIMILARITY: Belongs to the SRP19 family. {ECO:0000255|HAMAP-
CC       Rule:MF_00305}.
