GGAs (Golgi-localizing, gamma-adaptin ear homology domain, ARF-interacting, proteins) are critical for the transport of soluble proteins from the, trans-Golgi network (TGN) to endosomes/lysosomes by means of interactions, with TGN-sorting receptors, ADP-ribosylation factor (ARF), and clathrin., The amino-terminal VHS domains of GGAs form complexes with the cytoplasmic, domains of sorting receptors by recognizing acidic-cluster dileucine, (ACLL) sequences. Here we report the X-ray structure of the GGA1 VHS, domain alone, and in complex with the carboxy-terminal peptide of, cation-independent mannose 6-phosphate receptor containing an ACLL, sequence. The VHS domain forms a super helix with eight alpha-helices, similar to the VHS domains of TOM1 and Hrs. Unidirectional movements of, helices alpha6 and alpha8, and some of their side chains, create a set of, electrostatic and hydrophobic interactions for correct recognition of the, ACLL peptide. This recognition mechanism provides the basis for regulation, of protein transport from the TGN to endosomes/lysosomes, which is shared, by sortilin and low-density lipoprotein receptor-related protein.

[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>
