Reaction mechanism of Drosophila cryptochrome [PDF]
Proceedings of the National Academy of Sciences, 2010 Cryptochrome (CRY) is a blue-light sensitive flavoprotein that functions as the primary circadian photoreceptor in Drosophila melanogaster . The mechanism by which it transmits the light signal to the core clock circuitry is not known.

Cellular Metabolites Enhance the Light Sensitivity of Arabidopsis Cryptochrome through Alternate Electron Transfer Pathways [PDF]
, 2014 Cryptochromes are blue light receptors with multiple signaling roles in plants and animals. Plant cryptochrome (cry1 and cry2) biological activity has been linked to flavin photoreduction via an electron transport chain comprising three evolutionarily ...

GmBICs Modulate Low Blue Light-Induced Stem Elongation in Soybean
Frontiers in Plant Science, 2022 Blue-light inhibitors of cryptochromes (BICs) promote hypocotyl elongation by suppressing the activity of cryptochromes in Arabidopsis. Nevertheless, the roles of BICs in other plant species are still unclear.

UV Radiation in DNA Damage and Repair Involving DNA-Photolyases and Cryptochromes
Biomedicines, 2021 Prolonged exposure to ultraviolet radiation on human skin can lead to mutations in DNA, photoaging, suppression of the immune system, and other damage up to skin cancer (melanoma, basal cell, and squamous cell carcinoma).

Chemical compass model for avian magnetoreception as a quantum coherent device
, 2013 It is known that more than 50 species use the Earth's magnetic field for orientation and navigation. Intensive studies particularly behavior experiments with birds, provide support for a chemical compass based on magnetically sensitive free radical ...

Light-dependent magnetoreception in birds : increasing intensity of monochromatic light changes the nature of the response [PDF]
, 2007 Background The Radical Pair model proposes that magnetoreception is a light-dependent process. Under low monochromatic light from the short-wavelength part of the visual spectrum, migratory birds show orientation in their migratory direction.
