CC -!- FUNCTION: Component of the signal recognition particle (SRP) complex, a
CC ribonucleoprotein complex that mediates the cotranslational targeting
CC of secretory and membrane proteins to the endoplasmic reticulum (ER)
CC (By similarity). The SRP complex interacts with the signal sequence in
CC nascent secretory and membrane proteins and directs them to the
CC membrane of the ER (By similarity). The SRP complex targets the
CC ribosome-nascent chain complex to the SRP receptor (SR), which is
CC anchored in the ER, where SR compaction and GTPase rearrangement drive
CC cotranslational protein translocation into the ER (By similarity).
CC Binds the signal recognition particle RNA (7SL RNA), SRP72 binds to
CC this complex subsequently (By similarity). The SRP complex possibly
CC participates in the elongation arrest function (By similarity).
CC {ECO:0000250|UniProtKB:P38687, ECO:0000250|UniProtKB:Q9UHB9}.
CC -!- SUBUNIT: Heterodimer with SRP72 (By similarity). SRP68/SRP72
CC heterodimer formation is stabilized by the presence of 7SL RNA (By
CC similarity). Component of a signal recognition particle (SRP) complex
CC that consists of a 7SL RNA molecule of 300 nucleotides and six protein
CC subunits: SRP72, SRP68, SRP54, SRP19, SRP14 and SRP9 (By similarity).
CC Within the SRP complex, interacts (via C-terminus) with SRP72 (via N-
CC terminus) (By similarity). {ECO:0000250|UniProtKB:Q00004,
CC ECO:0000250|UniProtKB:Q9UHB9}.
CC -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000250|UniProtKB:Q9UHB9}.
CC Nucleus, nucleolus {ECO:0000250|UniProtKB:Q9UHB9}. Endoplasmic
CC reticulum {ECO:0000250|UniProtKB:Q9UHB9}.
CC -!- DOMAIN: The N-terminus is required for RNA-binding.
CC {ECO:0000250|UniProtKB:Q9UHB9}.
CC -!- SIMILARITY: Belongs to the SRP68 family. {ECO:0000305}.
