Clathrin is a triskelion-shaped protein that forms vesicles. Vesicles carry substances of importance to the cell’s maintenance that must remain isolated from the cytoplasm. These substances have to be safely trasported from one organelle to another so organelles can communicate to each other. Vesicles bud into the cytoplasm from an organelle’s surface, and then fuse with the target organelle.
Clathrin cages are composed of symmetrical three-legged components called triskelions. Clathrin doesn’t bind directly to a membrane to form vesicles, instead, it binds to adaptor proteins that recognize molecules on a membrane surface.
