Intracellular Protein Sorting and Transport very important in eukaryotes because of many compartments remember: polypeptides synthesized at ribosomes ribosomes located in the cytoplasm (whole cell except nucleus, plasma membrane, cell wall or extracellular matrix) but ribosomes are more specifically located in the cytosol (cytoplasm except all membrane surrounded compartments) But proteins occur in all compartments! How do they get there? And how does the cell know in which compartment they belong? (Remember: protein composition very different in different compartments)

Unformatted text preview: proteins are either synthesized on free ribosomes in the cytosol or they are synthesized on the membrane-bound ribosomes of the rough ER (Fig. 9.3) the membrane-bound ribosomes of the rough ER synthesize proteins that are localized in: ER Golgi Lysosomes Plasma membrane cell exterior the free ribosomes in the cytosol synthesize proteins that are localized in: Cytosol Nucleus Peroxisomes Mitochondria Chloroplasts...
