Study Notes
Synthesis of Membrane Components
- Lipids and proteins are synthesized in the endoplasmic reticulum (ER)
- Lipids are synthesized in the smooth endoplasmic reticulum (SER) and inserted into its membrane
- All proteins start synthesis in cytosolic ribosomes
- Cytosolic proteins are finished and remain in the cytosol
Cells and Proteins
- Transmembrane proteins have a signal sequence
- This signal sequence stops translation and directs the ribosome to the ER, creating rough ER (RER)
- Translation continues after docking, inserting the protein into the ER membrane
