Binding of SRP to the ribosome and the growing polypeptide chain results in a temporary cessation of protein synthesis. This is because SRP recognizes and binds to signal sequences on the nascent polypeptide chain, halting translation until the ribosome-SRP complex can dock with the endoplasmic reticulum (ER) for further protein processing and secretion.
