Anti-METAP2 antibodies are used in the immunodetection of the protein methionyl aminopeptidase 2. In humans, the canonical protein has a reported length of 478 amino acid residues and a mass of 52.9 kDa. Its subcellular localization is in the cytoplasm. Up to 3 different isoforms have been reported for this protein. It is notably widely expressed in many tissue types. It is a member of the Peptidase M24A protein family. Post-translational modifications have been described, including O-glycosylation. Synonyms for this target antigen include MNPEP, p67eIF2, methionine aminopeptidase 2, eIF-2-associated p67 homolog, initiation factor 2-associated 67 kDa glycoprotein, and MAP2. METAP2 gene orthologs have been reported in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species. A number of METAP2 antibodies have been mentioned in research publications and have associated citations. Western Blot is a widely used application for these antibodies. ELISA and Immunohistochemistry are also common applications.
