Cryptochrome cry
WebDec 4, 2014 · The blue-light sensitive photoreceptor cryptochrome (CRY) may act as a magneto-receptor through formation of radical pairs involving a triad of tryptophans. Previous genetic analyses of behavioral responses of Drosophila to electromagnetic fields using conditioning, circadian and geotaxis assays have lent some support to the radical … WebApr 29, 2024 · Cryptochromes are blue-light receptors that mediate photoresponses in plants. The genomes of most land plants encode two clades of cryptochromes, CRY1 and CRY2, which mediate distinct and overlapping photoresponses within the same species and between different plant species.

WebJun 15, 2013 · The circadian proteins CLOCK and BMAL1 heterodimerize and interact with E-box response elements in the promoters of target genes, which drive the positive transcription arm of the TTO loop. Two of these target genes encode the circadian proteins Period (Per) (homologs: 1, 2, and 3) and Cryptochrome (Cry) (homologs: 1 and 2). Some insects, including the monarch butterfly, have both a mammal-like and a Drosophila-like version of cryptochrome, providing evidence for an ancestral clock mechanism involving both light-sensing and transcriptional-repression roles for cryptochrome. Cry mutants have altered circadian rhythms, … See more Cryptochromes (from the Greek κρυπτός χρώμα, "hidden colour") are a class of flavoproteins found in plants and animals that are sensitive to blue light.
