Abstract

On emergence of the signal sequence of nascent secretory proteins from the large ribosomal subunit, translation is stopped by a cytoplasmic protein complex. A specific membrane protein of the endoplasmic reticulum, the ‘docking protein’, releases this block and allows further synthesis to be directly coupled to transfer across the membrane.
