Final answer:
Clathrin, V-SNARE proteins, and coat proteins are various proteins that regulate the process of vesicle formation.
Step-by-step explanation:
The process of vesicle formation is regulated by various proteins. One key protein involved is clathrin, which helps cargo protein-bound receptor proteins bud off from the trans Golgi stack, leading to vesicle formation.
Furthermore, V-SNARE proteins on vesicles bind to complementary T-SNARE proteins on receiving membranes, which facilitates the fusion of the membranes.
Finally, coat proteins and clathrin dissociate from secretory vesicles during fusion, allowing their contents to be released.
