Activation mechanism of Drosophila cryptochrome through an allosteric switch
Science Advances, 2021 Photoexcitation of FAD triggers ion-pair breakage and allosteric conformational change, leading to cryptochrome activation. Cryptochromes are signaling proteins activated by photoexcitation of the flavin adenine dinucleotide (FAD) cofactor.

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.

Frontiers in Ecology and Evolution, 2022 Cryptochromes are evolutionary ancient blue-light photoreceptors that are part of the circadian clock in the nervous system of many organisms. Cryptochromes transfer information of the predominant light regime to the clock which results in the fast ...

Structural Rearrangements of Pigeon Cryptochrome 4 Undergoing a Complete Redox Cycle
Journal of Physical Chemistry BCryptochrome is currently the major contender of a protein to underpin magnetoreception, the ability to sense the Earth’s magnetic field. Among various types of cryptochromes, cryptochrome 4 has been identified as the likely magnetoreceptor in migratory ...

Localisation of cryptochrome 2 in the avian retina
Journal of Comparative Physiology, 2021 Cryptochromes are photolyase-related blue-light receptors acting as core components of the mammalian circadian clock in the cell nuclei. One or more members of the cryptochrome protein family are also assumed to play a role in avian magnetoreception, but

One Actor, Multiple Roles: The Performances of Cryptochrome in Drosophila
Frontiers in Physiology, 2020 Cryptochromes (CRYs) are flavoproteins that are sensitive to blue light, first identified in Arabidopsis and then in Drosophila and mice. They are evolutionarily conserved and play fundamental roles in the circadian clock of living organisms, enabling ...

Genetic analysis of cryptochrome in insect magnetosensitivity
Frontiers in Physiology, 2022 The earth’s magnetic field plays an important role in the spectacular migrations and navigational abilities of many higher animals, particularly birds. However, these organisms are not amenable to genetic analysis, unlike the model fruitfly, Drosophila ...

Quantum Reports, 2021 The flavoprotein CRYPTOCHROME (CRY) is now generally believed to be a magnetosensor, providing geomagnetic information via a quantum effect on a light-initiated radical pair reaction.

Communications Biology, 2021 The volatile trail pheromone is an ephemeral chemical cue, whereas the geomagnetic field (GMF) provides a stable positional reference. However, it is unclear whether and how the cryptic termites perceive the GMF for orientation in light or darkness until

Communicative & Integrative Biology, 2010 It was recently discovered that the photoreceptor cryptochrome is involved in mediating magnetosensitive entrainment of the internal clock of fruit flies.1 This discovery follows other recent studies implicating a role of cryptochrome in mediating magnetic sensitivity in orientation responses of fruit flies2,3 and growth responses of plants.4 Such ...
