1. Actin
2. Beta tubulin
3. Vimentin
4. dynein

 How do proteins that are secreted get to their destination?

2. Nuclear localization signal, translocation into the phospholipid bilayer of the rough ER, followed by the vesicular transport through the endomembrane.
3. Signal sequence, translocation into the phospholipid bilayer of the rough ER, followed by the vesicular transport through the endomembrane system
4. Nuclear export signal, followed by direct budding through the endomembrane system
5. Signal sequence, translocation into the lumen of the rough ER, followed by the vesicular transport through the endomembrane system
