Photoentrainment in Mammals: A Role for Cryptochrome? [PDF]
Journal of Biological Rhythms, 1999 There is growing evidence in support of the hypothesis that, in mammals, photoreceptive tasks are segregated into those associated with creating a detailed visual image of the environment and those involved in the photic regulation of temporal biology. The hypothesis that this segregation extends to the use of different photoreceptors remains unproven,

Signaling Mechanisms by Arabidopsis Cryptochromes [PDF]
Frontiers in Plant Science, 2022 Cryptochromes (CRYs) are blue light photoreceptors that regulate growth, development, and metabolism in plants. In Arabidopsis thaliana (Arabidopsis), CRY1 and CRY2 possess partially redundant and overlapping functions. Upon exposure to blue light, the monomeric inactive CRYs undergo phosphorylation and oligomerization, which are crucial to CRY ...

Monte-Carlo wavefunction approach for the spin dynamics of recombining radicals
New Journal of Physics, 2020 We adapt the Monte-Carlo wavefunction (MCWF) approach to treat the open-system spin dynamics of radical pairs subject to spin-selective recombination reactions.

Reflections On Contributing To “Big Discoveries” About The Fly Clock: Our Fortunate Paths As Post-Docs With 2017 Nobel Laureates Jeff Hall, Michael Rosbash, And Mike Young [PDF]
, 2018 In the early 1980s Jeff Hall and Michael Rosbash at Brandeis University and Mike Young at Rockefeller University set out to isolate the period (per) gene, which was recovered in a revolutionary genetic screen by Ron Konopka and Seymour Benzer for mutants

Cryptochrome, Phytochrome, and Anthocyanin Production [PDF]
Plant Physiology, 1991 Anthocyanin production in cabbage (Brassica oleracea L.) and tomato (Lycopersicon esculentum Mill.) seedlings exposed to prolonged irradiations was studied under conditions that allowed discrimination, within certain limits, between the contribution of cryptochrome and phytochrome in the photoregulation of the response. The results of the study provide

Frontiers in Molecular Neuroscience, 2019 Circadian rhythms regulate many biological processes and play fundamental roles in behavior, physiology, and metabolism. Such periodicity is critical for homeostasis because disruption or misalignment of the intrinsic rhythms is associated with the onset

Eumetazoan Cryptochrome Phylogeny and Evolution [PDF]
Genome Biology and Evolution, 2015 Cryptochromes (Crys) are light sensing receptors that are present in all eukaryotes. They mainly absorb light in the UV/blue spectrum. The extant Crys consist of two subfamilies, which are descendants of photolyases but are now involved in the regulation of circadian rhythms. So far, knowledge about the evolution, phylogeny, and expression of cry genes

The structural and functional roles of the flavin cofactor FAD in mammalian cryptochromes
Frontiers in Molecular Biosciences, 2023 The importance of circadian rhythms in human health and disease calls for a thorough understanding of the underlying molecular machinery, including its key components, the flavin adenine dinucleotide (FAD)-containing flavoproteins cryptochrome 1 and 2 ...
