Clathrin: The Protein That Builds a Cage

How does a cell bring substances in from the outside?
Clathrin is a protein that assembles into a cage-like structure beneath the cell membrane. As clathrin molecules gather, they help bend the membrane and form a small vesicle that carries selected molecules into the cell.
Once the vesicle is released, the clathrin coat quickly disassembles and the proteins are recycled for the next round.
