clathrin

Clathrin is a protein that plays a key role in the process of cellular internalization. It forms a coated, basket-like structure on the surface of cells, helping to shape the membrane into small pockets or vesicles. These vesicles are used to transport materials like nutrients, receptors, or signals from outside the cell into its interior, or between different parts within the cell. Essentially, clathrin acts as a sculptor and transporter, ensuring that the cell efficiently takes in and manages various substances vital for its function and communication.
