Question

What are 4 ways coiled coil tethers form the golgi matrix?

Answer 1

Coiled coil tethers in the Golgi matrix form through binding of cargo receptor proteins, fusion of vesicles, packaging of secretory vesicles, and processing of packaged proteins.

Step-by-step explanation:

Coiled coil tethers are involved in the formation of the Golgi matrix through several ways:

1. Binding of cargo receptor proteins: Coiled coil tethers in the Golgi membranes bind to specific cargo receptor proteins. These cargo receptor proteins help to package and sort cargo proteins into separate vesicles with different destinations.
2. Fusion of vesicles: Once the cargo protein-bound receptor proteins bud off from the trans Golgi stack, the vesicles acquire membrane V-SNARE proteins. When V-SNARE proteins on the vesicles bind to complementary T-SNARE proteins on receiving membranes, the membranes fuse.
3. Packaging of secretory vesicles: The modified and tagged proteins are packaged into secretory vesicles that bud from the trans face of the Golgi. Some of these vesicles deposit their contents into other cell parts, while others fuse with the plasma membrane and release their contents outside the cell.
4. Processing of packaged proteins: Coiled coil tethers in the Golgi vesicle stack are involved in the processing of packaged proteins as they pass through the Golgi. This includes undergoing terminal glycosylation.
