ROLE OF CRYPTOCHROME-1 AND CRYPTOCHROME-2 IN ALDOSTERONE SECRETION
Journal of Hypertension, 2019Objective:Knock-out mice for the genes Cry1 and Cry2 lack the circadian clock components Cryptochrome-1 and Cryptochrome-2 and display a form of hyperaldosteronism sustained by the upregulation of type VI 3β-hydroxyl-steroid dehydrogenase (Hsd3b6).

The oligomeric structures of plant cryptochromes
Nature Structural & Molecular Biology, 2020Cryptochromes (CRYs) are a group of evolutionarily conserved flavoproteins found in many organisms. In plants, the well-studied CRY photoreceptor, activated by blue light, plays essential roles in plant growth and development. However, the mechanism of activation remains largely unknown.

Cryptochrome Structure and Signal Transduction
Annual Review of Plant Biology, 2003Cryptochromes are photosensory receptors mediating light regulation of growth and development in plants. Since the isolation of the Arabidopsis CRY1 gene in 1993, cryptochromes have been found in every multicellular eukaryote examined. Most plant cryptochromes have a chromophore-binding domain that shares similar structure with DNA photolyase, and a ...

DNA photolyases and cryptochromes
Mutation Research/DNA Repair, 2000This brief review gives an overview of the gene family of photolyases and cryptochromes, followed by a description of the main features of the three-dimensional structures of photolyases known to date. It then discusses recent biophysical studies of photolyase function, and modelling studies on the interaction between the enzyme and its substrate.

Molecular evolution of cryptochromes in fishes
Gene, 2015Circadian rhythmicity is an endogenous biological cycle of about 24h, which exists in cyanobacteria and fungi, plants and animals. Circadian rhythms improve the adaptability of organisms in both constant and changing environments. The cryptochrome (CRY) is a key element of the circadian system in various animal groups including fishes.

Partial Conversion of an Animal-Like Cryptochrome into a Plant Cryptochrome
The Journal of Physical Chemistry BCryptochromes act as flavin-binding photoreceptors in many organisms. The green alga Chlamydomonas reinhardtii contains both a plant cryptochrome (pCRY) and an animal-like cryptochrome (aCRY) with very distinct photochemistry. pCRY functions as a blue light receptor, whereas dual-function aCRY acts as a (6-4) photolyase and as a photoreceptor up to 680

Cryptochromes and Circadian Photoreception in Animals
2005Cryptochromes are flavin- and folate-containing blue-light photoreceptors with a high degree of similarity to DNA photolyase, which repairs ultraviolet-induced DNA damage using blue light to initiate the repair reaction. Cryptochromes play essential roles in the maintenance of circadian rhythms in mice and Drosophila, and genetic data indicate that ...
