The SRP receptor in the the endoplasmic reticulum (ER) membrane binds via its alpha subunit to the the SRP54 subunit of the Signal Recognition Particle (SRP), which itself is bound to a ribosome:mRNA:polypeptide complex. This interaction tethers the ribosome to the ER membrane, oriented so that the nacent polypeptide will traverse the ER membrane and enter the ER lumen. This process has been characterized in detail in cultured canine cells; this human event is inferred by homology from its canine counterpart.
