What molecules are likely to be found in the membrane of the rough endoplasmic reticulum? Rough endoplasmic reticulum (RER) is covered with ribosomes which are the site  If polyribosomes are permanently stationed, this would imply that local protein synthesis can occur at some synapses but not others. In prokaryotic cells, translation occurs only in the cytosol, and in eukaryotic cells translation may occur both in the cytosol and rough endoplasmic reticulum. When this is done . Central vacuole . This is followed by oligomerization between the ER and trans-Golgi network (depending on the connexin type) into connexons, which are then delivered to the membrane via the actin or microtubule networks. -cytosol.
