Messenger RNA injected Xenopus oocytes exhibit a differential capacity for translation. mRNAs translated in the free cytoplasm are translated efficiently whereas mRNAs translated on the rough endoplasmic reticulum (RER) membrane are translated inefficiently. If mRNA injected oocytes are injected additionally with proteins isolated from the RER, enhanced translation of RER-bound mRNAs is observed. When examined by sucrose gradient centrifugation and RNA dot blots, most of the injected RER-bound mRNA sediments less than or equal to the 80 S monosome. The RER proteins recruit these preinitiated mRNAs onto polysomes as evidenced by a shift in sedimentation to the polysome region of a sucrose gradient. When examined by immunoblotting, the RER proteins are shown to contain a protein which reacts specifically with an antibody directed against docking protein (SRP-receptor protein). However, this putative docking protein does not appear to be the protein which actually recruits the preinitiated mRNAs onto polysomes.
