Clathrin is a proteic complex found in coated pits and vesicles, organelles which are important in membrane trafficking functions such as endocytosis and Golgi sorting.

Clathrin is the main structural component of the lattice covering the cytoplasmic face of the coated pits and coated vesicles in which specific macromolecules are entrapped in the process of receptor-mediated endocytosis.

Clathrin is a large, soluble protein composed of heavy chains (CLTC) (molecular size, about 192 kD) and light chains CLTA and CLTB (molecular size, about 32-38 kD).
