FUNCTION: Component of the signal recognition particle (SRP) complex, a ribonucleoprotein complex that mediates the cotranslational targeting of secretory and membrane proteins to the endoplasmic reticulum (ER) (PubMed:34020957). The SRP complex interacts with the signal sequence in nascent secretory and membrane proteins and directs them to the membrane of the ER (PubMed:34020957). The SRP complex targets the ribosome-nascent chain complex to the SRP receptor (SR), which is anchored in the ER, where SR compaction and GTPase rearrangement drive cotranslational protein translocation into the ER (PubMed:34020957). Binds the signal recognition particle RNA (7SL RNA), SRP72 binds to this complex subsequently (PubMed:16672232, PubMed:27899666). The SRP complex possibly participates in the elongation arrest function (By similarity). {ECO:0000250|UniProtKB:P38687, ECO:0000269|PubMed:16672232, ECO:0000269|PubMed:27899666, ECO:0000269|PubMed:34020957}.
