Retina-specific copper amine oxidase (AOC2) is present on the cell surface of most cells but especially retinal cells. It is classed as a semicarbazide-sensitive amine oxidase (SSAO) and catalyses the oxidative deamination of aromatic amines such as tyramine (TYR, shown here), 2-phenylethylamine and tryptamine (Kaitaniemi et al. 2009, Bour et al. 2007). Overexpression of AOC2 could result in tissue destruction seen in ocular pathologies.
