Japanese eel, Anguilla japonica. Showing fluorescent colours when photographed under special blue or ultraviolet light and filter. Its muscle fibres produce the first fluorescent protein identified in a vertebrate. It's totally different” from other fluorescent proteins. For example, instead of producing light with a chromophore that is part of the protein sequence, as the classical Green Fluorescent Protein (GFP) does, UnaG fluoresces when it binds a naturally occurring small molecule called bilirubin, a breakdown product of haemoglobin used in hospital tests for decades to assess liver function and diagnose diseases such as jaundice.

Ses fibres musculaires produisent la première protéine fluorescente identifiée chez un vertébré. C'est totalement différent des autres protéines fluorescentes. Par exemple, au lieu de produire de la lumière avec un chromophore faisant partie de la séquence protéique, comme le fait la protéine GFP (Green Fluorescent Protein) classique, UnaG devient fluorescent lorsqu'il se lie à une petite molécule naturelle appelée bilirubine, un produit de dégradation de l'hémoglobine utilisé à l'hôpital tests pendant des décennies pour évaluer la fonction hépatique et diagnostiquer des maladies telles que la jaunisse.
