Anti-EEF1A2 antibodies are used in the immunodetection of the protein eukaryotic translation elongation factor 1 alpha 2. In humans, the canonical protein has a reported length of 463 amino acid residues and a mass of 50.5 kDa. Its subcellular localization is in the nucleus. It is notably expressed in many tissues, such as the caudate and cerebellum. A member of the Classic translation factor GTPase protein family, EEF1A2 is known to promote the GTP-dependent binding of aminoacyl-tRNA to the A-site of ribosomes during protein biosynthesis. Post-translational modifications have been described, including methylation. The EEF1A2 gene has been associated with the disease, Developmental and epileptic encephalopathy. Synonyms for this target antigen include EEF1AL, EF-1-alpha-2, EF1A, EIEE33, HS1, MRD38, STN, and DEE33. EEF1A2 gene orthologs have been reported in the mouse, rat, bovine, frog, chimpanzee and chicken species.
