Anti-GGA3 Antibody

GGA3 (also known as ADP-ribosylation factor binding protein GGA3, Golgi-localized, gamma ear-containing, ARF-binding protein 3, Gamma-adaptin related protein 3) plays a role in protein sorting and trafficking between the trans-Golgi network (TGN) and endosomes. This protein 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. GGA1 is a monomeric protein that interacts with SORT1, SORL1, LRP3, GGA binding partner (GGABP) and P200, GGA1 and GGA2 as well as RABEP1, RABGEF1 and type-I membrane proteins M6PR/CD-MPR, IGF2R/CI-MPR and BACE1. GGA3 is a ubiquitously expressed membrane-associated protein that is localized to TGN and endosomes. Multiple alternatively spliced transcript variants encoding different isoforms have been found for this gene.

This affinity-purified antibody was prepared from whole rabbit serum produced by repeated immunizations with a synthetic peptide corresponding to an internal region near amino acids 400-425 of Human GGA3.

This affinity purified antibody is directed against human GGA3 protein. The product was affinity purified from monospecific antiserum by immunoaffinity purification. A BLAST analysis was used to suggest reactivity with this protein from human and chimpanzee based on 100% homology for the immunogen sequence. Cross-reactivity may occur with GGA3 from macaque (93% homology) and orangutan (87% homology) sources. The immunizing sequence is present on both the long (isoform 1) and short (isoform 2) transcript variants for this protein.
