Verified step by step guidance

Understand that protein coats are involved in vesicle formation and transport within cells. They help in the budding of vesicles from membranes and in selecting cargo molecules.

Familiarize yourself with the common types of protein coats: COPI, COPII, and Clathrin. Each has a specific role in cellular transport.

COPI is involved in retrograde transport, moving vesicles from the Golgi apparatus back to the endoplasmic reticulum.

COPII is responsible for anterograde transport, moving vesicles from the endoplasmic reticulum to the Golgi apparatus.

Clathrin is involved in the formation of vesicles at the plasma membrane and the trans-Golgi network. Note that COPIII is not a recognized protein coat, indicating it is not involved in these processes.
