[https://www.uniprot.org/uniprot/GGA1_HUMAN GGA1_HUMAN] Plays a role in protein sorting and trafficking between the trans-Golgi network (TGN) and endosomes. Mediates the ARF-dependent recruitment of clathrin to the TGN and binds ubiquitinated proteins and membrane cargo molecules with a cytosolic acidic cluster-dileucine (AC-LL) motif.<ref>PMID:11301005</ref>

The GGAs are a family of clathrin adaptor proteins involved in vesicular transport between the trans-Golgi network and endosomal system. Here we confirm reports that GGAs are targeted to the Golgi via interaction between the GGA-GAT domain and ARF-GTP, and we present the structure of the GAT domain of human GGA1, completing the structural description of the folded domains of GGA proteins. The GGA-GAT domain possesses an all alpha-helical fold with a "paper clip" topology comprising two independent subdomains. Structure-based mutagenesis demonstrates that ARF1-GTP binding by GGAs is exclusively governed by the N-terminal "hook" subdomain, and, using an in vitro recruitment assay, we show that ARF-GTP binding by this small structure is required and sufficient for Golgi targeting of GGAs.
