The W420 tryptophan residue located closest to the FAD-dCRY interaction site is critical for blue- and UV-light-evoked electrophysiological responses, while other tryptophan residues within electron transfer distance to W420 do not appear to be required for light-evoked electrophysiological responses.

we identify the circadian blue-light photoreceptor CRYPTOCHROME as a molecular regulator of Prolonged Morning Wakefulness (PMW), and propose a model in which the Drosophila nervous system integrates information encoding temperature, light, and time to dynamically control when sleep is initiated. Our results provide a platform to investigate how environmental inputs co-ordinately regulate sleep plasticity.

The findings of this article for the first time define CRY expression in Drosophila peripheral tissues and reveal that CRY acts together with K(+) channels to maintain passive membrane properties in a non-clock-containing peripheral tissue independent of light.
