Anti-MEOX2 antibodies are used in the immunodetection of the protein mesenchyme homeobox 2. In humans, the canonical protein has a reported length of 304 amino acid residues and a mass of 33.6 kDa. Its subcellular localization is in the nucleus. It is notably expressed in the placenta. MEOX2 is known to be involved with angiogenesis and limb development. Synonyms for this target antigen include MOX2, homeobox protein MOX-2, growth arrest-specific homeobox, and GAX. MEOX2 gene orthologs have been reported in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species.
