Based on the light-reactive behavior of siliceous sponges, their intriguing quartz glass-based spicular system and the existence of a light-generating luciferase [Mu ¨ller WEG et al.(2009) Cell Mol Life Sci66, 537–552], a pro-tein potentially involved in light reception has been identified, cloned and recombinantly expressed from the demosponge Suberites domuncula. | A cryptochrome-based photosensory system in the siliceous sponge Suberites domuncula Demospongiae Werner E.

Its sequence displays two domains characteristic of cryptochrome the N-ter-minal photolyase-related region and the C-terminal FAD-binding domain. The expression level of S. domuncula cryptochrome depends on animal s exposure to light and is highest in tissue regions rich in
