GGA1 Rabbit Polyclonal Antibody

ADP-ribosylation factor-binding protein GGA1 is a protein that in humans is encoded by the GGA1 gene. This gene encodes a member of the Golgi-localized, gamma adaptin ear-containing, ARF-binding (GGA) protein family. Members of this family are 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. Multiple alternatively spliced transcript variants encoding different isoforms have been found for this gene. GGA1 has been shown to interact with Sortilin 1, BACE2, RABEP1 and ARF3.
