SRP is a ribonucleoprotein particle essential for the translation and integration in membranes of signal peptide-bearing proteins. SRP is composed of an RNA backbone, on which bind different proteins. | SRP is a ribonucleoprotein particle essential for the translation and integration in membranes of signal peptide-bearing proteins.
