    The mammalian signal recognition particle (SRP) is an essential cytoplasmic ribonucleoprotein complex involved in targeting signal-peptide-containing proteins to the endoplasmic reticulum. Assembly of the SRP requires protein SRP19 to bind first to helix 6 of the SRP RNA before the signal-peptide-recognizing protein, SRP54, can bind to helix 8 of the RNA. Helix 6 is closed by a GGAG tetraloop, which has been shown to form part of the SRP19-binding site.
