To accommodate daily recurring environmental changes, animals show cyclic variations in
behaviour and physiology, which include prominent behavioural states such as sleep–wake …

Cryptochromes are flavoprotein photoreceptors first identified in Arabidopsis thaliana, where
they play key roles in growth and development. Subsequently identified in prokaryotes …

Three major classes of flavin photosensors, light oxygen voltage (LOV) domains, blue light
sensor using FAD (BLUF) proteins and cryptochromes (CRYs), regulate diverse biological …

Cryptochromes are photolyase-like blue light receptors originally discovered in Arabidopsis
but later found in other plants, microbes, and animals. Arabidopsis has two cryptochromes …

Computational and biochemical studies implicate the blue-light sensor cryptochrome (CRY)
as an endogenous light-dependent magnetosensor enabling migratory birds to navigate …

Understanding the biophysical basis of animal magnetoreception has been one of the
greatest challenges in sensory biology. Recently it was discovered that the light-dependent …

Drosophila cryptochrome (dCRY) is a FAD-dependent circadian photoreceptor, whereas
mammalian cryptochromes (CRY1/2) are integral clock components that repress …

Since 1960, magnetic fields have been discussed as Zeitgebers for circadian clocks, but the
mechanism by which clocks perceive and process magnetic information has remained …

Flavin coenzymes are universally found in biological redox reactions. DNA photolyases, with
their flavin chromophore (FAD), utilize blue light for DNA repair and photoreduction. The …

DNA photolyase uses visible light and a fully reduced flavin cofactor FADH− to repair major
UV-induced lesions in DNA, the cyclobutane pyrimidine dimers (CPDs). Electron transfer …
