Crystal structure of human gamma1-adaptin ear domain

Overview

The adaptor proteins AP-1 and GGA regulate membrane traffic between the, trans-Golgi network (TGN) and endosomes/lysosomes through ARF-regulated, membrane association, recognition of sorting signals, and recruitment of, clathrin and accessory proteins. The gamma 1-adaptin subunits of AP-1 and, GGA possess homologous ear domains involved in the recruitment of, accessory proteins, gamma-synergin and Rabaptin-5. The crystal structure, of the human gamma 1-adaptin ear domain consists solely of an, immunoglobulin-like fold, unlike the alpha-adaptin ear domain., Structure-based mutational analyses reveal a binding site for the, accessory proteins that is composed of conserved basic residues, indicating that the recruitment mechanism in gamma 1-adaptin and GGA is, distinct from that in alpha-adaptin.
