The bead-attached cells were ruptured by sonication for 15 s, washed with 0.5 M tris-HCl pH 7.0, 1 mM dithiothreitol and then with cytosolic buffer, and finally resuspended in 500 μl of cytosolic buffer.

    • AP-2 and AP-1 adaptor proteins were prepared by separation of the clathrin coat proteins (3 mg/ml) on a Sepharose CL4B gel filtration column in 0.5 M tris-HCl pH 7.4. The adaptor (AP-2 plus AP-1) and clathrin peaks were pooled and concentrated to 0.5 mg/ml and 1 mg/ml, respectively, and either used directly or frozen in liqid nitrogen and stored at70°C.
