Cryptochrome signaling
Cryptochromes (from the Greek κρυπτός χρώμα, "hidden colour") are a class of flavoproteins found in plants and animals that are sensitive to blue light. They are involved in the circadian rhythms and the sensing of magnetic fields in a number of species. The name cryptochrome was proposed as a portmanteau … See more Although Charles Darwin first documented plant responses to blue light in the 1880s, it was not until the 1980s that research began to identify the pigment responsible. In 1980, researchers discovered that the HY4 gene of the plant See more Phototropism In plants, cryptochromes mediate phototropism, or directional growth toward a light source, in response to blue light. This response is … See more Cryptochromes (CRY1, CRY2) are evolutionarily old and highly conserved proteins that belong to the flavoproteins superfamily that … See more • cryptochrome at the U.S. National Library of Medicine Medical Subject Headings (MeSH) • Cryptochrome circadian clock in Monarch Butterflies Archived 2011-11-21 at the Wayback Machine, by Steven M.

However, most cryptochromes do not repair DNA and instead have developed novel roles in signaling.
