Abstract.
The clathrin-associated adaptor protein (AP) complexes drive the polymerization of clathrin in coated pits to form coated vesicles. It has previously been shown that the carboxyl-terminal hinge/ear domain of the β2 chain contains a binding site for clathrin and that removal of this domain from APs or from isolated β2 chains abrogates their ability to form clathrin coats in vitro. We show here that the hinge/ear domain is necessary for efficient incorporation of AP complexes into coated pits and coated vesicles in cells, a result that is consistent with the view that the β chains indeed provide an important interaction between the AP complexes and clathrin.
