Anti-EIF2B3 antibodies are used in the immunodetection of the protein eukaryotic translation initiation factor 2B subunit gamma. In humans, the canonical protein has a reported length of 452 amino acid residues and a mass of 50.2 kDa. Up to 3 different isoforms have been reported for this protein. It is notably widely expressed in many tissue types. A member of the EIF-2B gamma/epsilon subunits protein family, EIF2B3 is known to catalyze the exchange of eukaryotic initiation factor 2-bound GDP for GTP. Synonyms for this target antigen include EIF2Bgamma, VWM3, translation initiation factor eIF-2B subunit gamma, eIF-2B GDP-GTP exchange factor subunit gamma, eukaryotic translation initiation factor 2B, subunit 3 gamma, 58kDa, and EIF-2B. EIF2B3 gene orthologs have been reported in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species. A number of EIF2B3 antibodies have been mentioned in research publications and have associated citations. Western Blot is a widely used application for these antibodies. Immunofluorescence and Immunohistochemistry are also common applications.
