Reflectins are a family of intrinsically disordered proteins evolved by a certain number of cephalopods including Euprymna scolopes and Doryteuthis opalescens to produce iridescent camouflage and signaling. The recently identified protein family is enriched in aromatic and sulfur-containing amino acids, and is utilized by certain cephalopods to refract incident light in their environment. The reflectin protein is responsible for dynamic pigmentation and iridescence in organisms. This process is “dynamic” due to its reversible properties, allowing reflectin to change an organism’s appearance in response to external factors such as needing to camouflage or send warning signals.

- Les réflectines constituent une famille de protéines complexes, capables de brusques changements de forme, qui modifient l'incidence de la lumière qu'elles réfléchissent (lumière solaire, artificielle ou provenant de l'organisme lui-même (bioluminescence). Elles ont été récemment découvertes par des universitaires californiens dans les ou iridophores du tégument de l'espèce de calmar nain (30 millimètres) Euprymna scolopes (qui vit dans le centre de l'océan Pacifique), mais ensuite retrouvée chez d'autres espèces de céphalopodes dont certaines peuvent afficher des motifs colorés éblouissants et rapidement changeants, a priori en contractant sélectivement certains muscles peauciers pour activer de façon réversible les chromatophores - cellules contenant des pigments.

The reflectin protein is responsible for dynamic pigmentation and iridescence in organisms. This process is “dynamic” due to its reversible properties, allowing reflectin to change an organism’s appearance in response to external factors such as needing to camouflage or send warning signals. Reflectin proteins are likely distributed in the outer layer of cells called "sheath cells" that surround an organism’s pigment cells also known as chromatocyte. Specific sequences of reflectin ables cephalopods to communicate and camouflage by adjusting color and reflectivity. (en)
