DESCRIPTION

Also known as GGA3_HUMAN, GGA3, KIAA0154. 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 (DXXLL) motif (PubMed:11301005). Mediates export of the GPCR receptor ADRA2B to the cell surface (PubMed:26811329). nvolved in BACE1 transport and sorting as well as regulation of BACE1 protein levels (PubMed:17553422, PubMed:15615712, PubMed:20484053). Regulates retrograde transport of BACE1 from endosomes to the trans-Golgi network via interaction through the VHS motif and dependent of BACE1 phosphorylation (PubMed:15615712). Modulates BACE1 protein levels independently of the interaction between VHS domain and DXXLL motif through recognition of ubiquitination (PubMed:20484053). Key player in a novel DXXLL-mediated endosomal sorting machinery to the recycling pathway that targets NTRK1 to the plasma membrane (By similarity). Monomer (Probable). Interacts with GGA1 and GGA2 (PubMed:14638859). Binds to clathrin and activated ARFs, such as ARF1, ARF5 and ARF6 (PubMed:11301005, PubMed:11950392). Binds RABEP1 and RABGEF1 (PubMed:12505986, PubMed:15143060). Interacts with the membrane proteins M6PR/CD-MPR and IGF2R/CI-MPR and the accessory proteins SYNRG, EPN4, NECAP1, NECAP2 and AFTPH/aftiphilin (PubMed:10814529, PubMed:11387475, PubMed:12060753, PubMed:12213833, PubMed:14665628). Interacts with TSG101 and UBC (PubMed:14660606, PubMed:15039775). Interacts with ADRA2B (PubMed:26811329). Interacts with NTRK1; the interaction is independent of NTRK1 activation and ubiquitination (PubMed:26446845). Interacts (via VHS domain) with BACE1 (via DXXLL motif) (PubMed:14567678).
