In the video Exploring the Endoplasmic Reticulum: Functions, Vesicle Trafficking, and Quality Control, I look at the important role played in the cell by the Endoplasmic Reticulum (ER).
The endoplasmic reticulum (ER) is involved in a number of key processes in the cell connected with protein production, including:
- Disulphide Bond Formation: Occurs as proteins are imported into the ER, crucial for protein stability and function.
- Protein Glycosylation: Starts in the ER and finishes in the Golgi, important for protein folding and interactions.
- Quality Control: Marks incorrectly folded proteins for destruction, though it may sometimes incorrectly target properly folded proteins.
The newly made proteins are trafficked from the ER to the Golgi in COPII Vesicles.
