Cryptochrome magnetoreception: four tryptophans could be better than three
Journal of the Royal Society Interface, 2021 The biophysical mechanism of the magnetic compass sensor in migratory songbirds is thought to involve photo-induced radical pairs formed in cryptochrome (Cry) flavoproteins located in photoreceptor cells in the eyes.

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 ...

Frontiers in Neuroscience, 2023 The mammalian circadian system generates an approximate 24-h rhythm through a complex autoregulatory feedback loop. Four genes, Period1 (Per1), Period2 (Per2), Cryptochrome1 (Cry1), and Cryptochrome2 (Cry2), regulate the negative feedback within this ...

Arabidopsis Cryptochrome 1 Controls Photomorphogenesis through Regulation of H2A.Z Deposition.
The Plant Cell, 2021 Light is a key environmental cue that fundamentally regulates plant growth and development, which is mediated by the multiple photoreceptors including the blue light photoreceptor cryptochrome 1 (CRY1).

Cryptochrome-1 expression: a new prognostic marker in B-cell chronic lymphocytic leukemia
Haematologica, 2009 Chronic lymphocytic leukemia is an adult-onset leukemia with a heterogeneous clinical behavior. When chronic lymphocytic leukemia cases were divided on the basis of IgVH mutational status, widely differing clinical courses were revealed.

Seasonally Changing Cryptochrome 1b Expression in the Retinal Ganglion Cells of a Migrating Passerine Bird. [PDF]
PLoS ONE, 2016 Cryptochromes, blue-light absorbing proteins involved in the circadian clock, have been proposed to be the receptor molecules of the avian magnetic compass.

Cryptochrome Signaling in Plants† [PDF]
Photochemistry and Photobiology, 2007 Cryptochromes are blue light receptors that mediate various light-induced responses in plants and animals. They share sequence similarity to photolyases, flavoproteins that catalyze the repair of UV light-damaged DNA, but do not have photolyase activity.

Molecular Cloning and Linkage Mapping of Cryptochrome Multigene Family in Soybean
The Plant Genome, 2009 The cryptochromes are a family of blue light photoreceptors that play important roles in the controls of plant development. Seven full-length cryptochrome cDNAs (GmCRY1a, GmCRY1b, GmCRY1c, GmCRY1d, GmCRY2a, GmCRY2b, and GmCRY2c) were isolated by cDNA ...

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 ...
