In the medical field, a Signal Recognition Particle (SRP) is a ribonucleoprotein complex that plays a crucial role in the targeting and insertion of membrane-bound and secretory proteins into the endoplasmic reticulum (ER) during protein synthesis. The SRP is composed of five polypeptide subunits and a small RNA molecule. It recognizes a specific signal sequence, called the signal peptide, that is present on the nascent polypeptide chain as it emerges from the ribosome during translation. Once the SRP binds to the signal peptide, it moves to the ER membrane, where it interacts with a receptor protein called the SRP receptor. This interaction triggers the release of the SRP from the signal peptide and the ribosome, allowing the ribosome to continue translating the protein. The SRP receptor then recruits a coat protein complex called COPII, which assembles into a vesicle that transports the membrane-bound or secretory protein to the ER lumen for further processing and folding. Disruptions in the function of the SRP or its components can lead to various diseases, including congenital disorders of glycosylation, which are caused by defects in the glycosylation of proteins.
