Two articles which succinctly describe how proteins enter the ER lumen.

The ER exists in two distinct morphologically different forms: the rough ER and the smooth ER. These are clearly distinguishable in electron micrographs by the presence of numerous ribosomes attached to the rough endoplasmic reticulum (RER) which give it its 'rough' appearance. 37). 38). The functions of the cytosol are described more fully later. The ER is involved in the biosynthesis, modification and transport of materials throughout the cell.
