The signal recognition particle (SRP) receptor is an integral membrane protein of the endoplasmic reticulum which, in conjunction with SRP, ensures the correct targeting of nascent secretory proteins to this membrane system. From the complementary DNA sequence we have deduced the complete primary structure of the SRP receptor and established that its amino-terminal region is anchored in the membrane. The anchor fragment and the cytoplasmic fragment contribute jointly to a functionally important region which is highly charged and may function in nucleic acid binding.
