Previous GeneCards Identifiers for GGA2 Gene
This gene encodes a member of the Golgi-localized, gamma adaptin ear-containing, ARF-binding (GGA) family. This family includes ubiquitous coat proteins that regulate the trafficking of proteins between the trans-Golgi network and the lysosome. These proteins share an amino-terminal VHS domain which mediates sorting of the mannose 6-phosphate receptors at the trans-Golgi network. They also contain a carboxy-terminal region with homology to the ear domain of gamma-adaptins. This family member may play a significant role in cargo molecules regulation and clathrin-coated vesicle assembly. [provided by RefSeq, Jul 2008]
GeneCards Summary for GGA2 Gene
GGA2 (Golgi Associated, Gamma Adaptin Ear Containing, ARF Binding Protein 2) is a Protein Coding gene. Diseases associated with GGA2 include 3-Methylglutaconic Aciduria, Type Iv and 3-Methylglutaconic Aciduria, Type Vii. Among its related pathways are Vesicle-mediated transport and TBC/RABGAPs. Gene Ontology (GO) annotations related to this gene include ADP-ribosylation factor binding. An important paralog of this gene is GGA1.
UniProtKB/Swiss-Prot Summary for GGA2 Gene
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:10747088). Mediates export of the GPCR receptor ADRA2B to the cell surface (PubMed:27901063). Regulates retrograde transport of phosphorylated form of BACE1 from endosomes to the trans-Golgi network (PubMed:15615712).
